Frequently Asked Questions - Promax 40 II MCCULLOCH

How do I start the chainsaw when the engine is cold?

Move the stop switch up, slide the choke lever to CLOSED, press the decompression valve if fitted, engage the throttle advance (depress throttle trigger and lock, then push the throttle advance backward), hold the saw firmly, and pull the starter rope until the engine fires once. Then move the choke to OPEN, pull again until it starts, and let it warm up for 10 seconds before use.

What fuel mix should I use for the McCulloch Promax 40 II?

Use a 2-stroke fuel mix: leaded or unleaded petrol (minimum 90 octane) mixed with 2-stroke oil. Recommended ratio is 40:1 (2.5% oil) or check the manual for specific oil types. Always use fresh mix and shake vigorously before each use.

How do I adjust the chain tension?

Loosen the bar retaining nuts, turn the chain adjuster screw (either standard or INTENZ system) so that when you lift the chain, an entire drive link is just visible. The chain should have no slack on the underside and must run freely in the bar groove. Tighten the nuts while pushing the bar tip upward.

How do I sharpen the chain?

Use a round file of the correct size (5/32" or 3/16") held at angles: top angle 30–35°, side angle 85–90°, and internal angle 60°. File each cutter tooth with the same number of strokes, from inside to outside. After several sharpenings, check the depth gauge height (0.65 mm below top edge) using a flat file and depth gauge tool.

What should I do if the engine won't start?

First check that the stop switch is in the ON position (I). Ensure there is at least 25% fuel in the tank. Clean the air filter if clogged. Remove and dry the spark plug, clean it, and check the gap. If these steps don't work, adjust the carburetor screws or contact your dealer.

How do I clean the air filter?

Remove the air filter cover, take out the foam filter, and wash it in petrol (do not use oil-mixed fuel). Alternatively, clean with compressed air. If the filter is damaged or does not seal tightly, replace it.

What type of chain oil should I use?

Use medium-viscosity chain lubricating oil, preferably McCulloch special oil. Never use waste oil as it damages the bar, chain, and oil pump. Refill the oil tank each time you refuel.

How do I engage and test the chain brake?

The chain brake is disengaged (lever pulled back) for normal operation. To engage manually, push the brake lever forward (recommended only at idle). Test the brake by starting the saw at idle, then push the lever forward – the chain should stop immediately. If not, do not use the saw and contact a dealer.

How do I adjust the carburetor?

The carburetor has three screws: L (low speed), H (high speed), and I (idle). Start by closing L and H gently clockwise, then open 1 full turn counterclockwise. For smoother acceleration, open L another 1/8 turn. Adjust idle speed to 2,800 min⁻¹ using screw I. Contact a dealer for major adjustments.

What safety precautions should I take when using this chainsaw?

Always wear approved safety glasses, helmet, ear defenders, gloves, and sturdy boots. Hold the saw with both hands, maintain a firm foothold, and never cut above shoulder height. Avoid kickback by not cutting with the bar nose. Keep bystanders and animals at least 10 m away. Read the full manual before use.

SAFETY PRECAUTIONS

B

1 All operators should read this manual carefully before using this chainsaw; only use this machine for usage specifically mentioned in this manual.

Wear suitable clothing. This should include snugly-fitting (safety) clothing, sturdy boots, heavy duty gloves, goggles or a face screen and ear plugs or ear mufflers. Wear a helmet if there is risk of falling objects or projections from trees.

2 Always hold the chainsaw firmly with both hands when the engine is running. Always maintain a firm foothold. Ensure you are able to stop the engine quickly if necessary. Do not work up a tree unless you have received suitable training and have the appropriate equipment (belts, ropes, safety hooks etc.) for this type of work.

We strongly recommend that all first-time chainsaw users obtain practical instruction on safe chainsaw usage before operating the chainsaw.

Do not operate this machine when tired or under the influence of any substances, drugs or alcohol which can impair vision, dexterity or judgement.

Prolonged use of chainsaws or other machines exposing the operator to vibration may produce Whitefinger's Disease (Raynaud's Phenomenon). This may reduce the hands' ability to feel and regulate temperature and may

produce general numbness. Continual or regular users should therefore monitor closely the condition of their hands or fingers. If any of the symptoms appear, seek immediate medical advice.

3 Never carry the chainsaw with the engine running. Whenever carrying a chainsaw, even for short distances, the chain should be covered by the chain guard (scabbard) and the bar should point backwards. When transporting the chainsaw in a vehicle, secure the saw to prevent fuel spillage.
4 To avoid kick-back, do not attempt to cut with the nose of the bar. Ensure the engine is running at full throttle before commencing to cut. To avoid kick-back, do not let the nose of the bar come into contact with logs, branches, the ground or any other obstruction. Do not allow any part of the chain to come into contact with rock, nails or wire fence Ensure the chain is kept sharp and correctly tensioned. Keep the spike or the saw body against the wood when cutting. Use only genuine accessories and spare parts. We recommend you have your unit periodically checked and serviced by an authorised dealer. Do not use chainsaw above shoulder height.
5 Do not operate the chainsaw near a naked flame or spilled fuel. Only operate the chainsaw outside and in well ventilated areas. After re-fuelling, always wipe off any spilled fuel. Move the chainsaw away from the fuelling point before starting the engine.
6 Keep by-standers and animals out of the work area; at a minimum distance of 10 m or twice the timber length. If necessary, use warning signs to keep on-lookers at a distance. Carefully survey the working site to note any hazards, eg. roads, paths, electricity cables, dangerous trees etc. Do not use the chainsaw if the device for stopping the chain (safety chainbrake) does not work correctly. Never place hands on the chain whilst the engine is running. Ensure someone is within hearing distance in case of an accident. If this is not possible, it is recommended that users operating chainsaws in remote areas carry an adequate first-aid kit with them and ensure someone knows their location. Never leave the engine running while the tool is unattended. ONLY USE ORIGINAL SPARE PARTS AND ACCESSORIES.

BAR AND CHAIN INSTALLATION - INTENZ

Ensure engine is always switched off before fitting or adjusting chain. Wear a pair of protective gloves when fitting or adjusting chain.

1 Ensure chain brake lever is in disengaged position (A). Remove retaining nuts (B) and cover.
2 Turn the adjusting screw (D) counterclockwise taking it fully back.
3 Feed chain into bar groove ensuring correct direction of chain (P).

4 Work the chain around sprocket and set the bar as illustrated, make the lower hole (F) coincide with the pin (G) of the adjusting screw.
5 Reposition side cover. Fit spike as illustrated.
6 Lock nuts (B) finger tight. Adjust chain tension pin by turning screw (D) so that when lifting the chain an entire drive link is just visible. The chain is correctly tensioned when there is no slack on the underside of the bar, and it runs freely in bar groove. Tighten the bar retaining nuts with the wrench, pushing bar tip upwards.

INTENZ

Turn the adjusting screw (I) counterclockwise taking it fully back.

Feed chain into bar groove ensuring correct direction of chain (P).

Lock nuts (B) finger tight.

Adjust chain tension pin by turning screw (l) so that when lifting the chain an entire drive link is just visible.

The chain is correctly tensioned when there is no slack on the underside of the bar, and it runs freely in bar groove. Tighten the bar retaining nuts with the wrench, pushing bar tip upwards.

FUEL MIX

D

Use only fuel recommended by this manual. This product is fitted with a 2-stroke engine and therefore requires a 2-stroke petrol and oil mix. Use leaded (4 Star) or unleaded petrol with a minimum octane rating of 90.

UNLEADED PETROL: if using unleaded petrol, you must use a totally synthetic 2-stroke engine oil or branded 2-stroke engine oil (see table).

Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol.

IMPORTANT

Always shake this fuel mix vigorously each time you use it. We recommend to carry out this operation each time you use the fuel.

Fuel mix properties deteriorate with time, we therefore recommend that you only make the quantity of fuel mix you will need for each usage. Do not use fuel mix more than a week old as this could damage the engine.

WARNING

Do not smoke when re-fuelling.

Always open the fuel cap slowly.

Re-fuel in open spaces only, keeping away from naked flames or sparks.

Always store fuel in an approved container.

SAFE STORAGE OF FUEL

Petrol is highly inflammable. Put out all cigarettes, pipes and cigars before working with petrol. Avoid spilling petrol. Store fuel in a cool, well ventilated place, in an approved container specifically designed for the purpose.

Never store engine with fuel in the tank in enclosed, poorly ventilated areas, where fuel fumes may reach an open flame, spark or pilot light such as in a furnace, water heater, clothes dryer etc. Petrol fumes can cause an explosion or a fire. Do not store large amounts of fuel.

CHAIN LUBRICATION

IMPORTANT

The service life of the bar and chain depends on good lubrication.

Always use chain lubricating oil of medium viscosity. We recommend special McCulloch chain lubricating oil.

Never use waste oil for this purpose. This results in damage to the bar, the chain and the oil pump.

Refill the chain oil tank each time the saw is refuelled.

To prevent possible restarting problems avoid running the fuel tank dry. This also helps to extend engine life.

NOTE: Saw chain stretches during use particularly when it is new, and it will occasionally be necessary to adjust and tighten it. A new chain will require adjustment after about 5 minutes of operation.

The mechanical oil pump for chain lubrication can be adjusted.

The feed rate of the chain oil pump can be adjusted by means of the regulating screw (A) (see details in the illustration).

STARTING AND STOPPING

E

IMPORTANT

Never start or operate unless bar and chain are properly installed. Before starting always move the saw away from the fuelling area and place it on a firm, flat surface, the guide bar to the front.

STARTING A COLD ENGINE

1 Check that the chain brake is in the disengaged position moving the lever (L) towards the front handle. Move the stop switch upwards.
2 Slide the choke lever (A) to the CLOSED position (OUT). Push the decompression valve (D) down if your models is fitted with one.
3 Depress throttle trigger lock out (S). Depress throttle trigger (G) and then operate throttle advance (P) moving it backwards.
4 Hold the saw firmly as shown in illustration and pull the starter rope until the engine fires once. Beware of moving chain!
5 Move choke lever (A) to the OPEN position (IN). Push the decompression valve (D) down if your models is fitted with one.
Pull the starter rope until the engine starts.
Allow engine to warm up for ten seconds for better cutting performance.
Squeeze the throttle trigger (G) to release the throttle advance. If engine fails to start, repeat these instructions.
6 The engine is stopped by depressing the STOP switch to STOP position.

After lengthy use of the chain at full speed, we recommend to run the engine for a few seconds at idle speed before stopping it.

STARTING A WARM ENGINE

Check that the ignition switch is not in the "stop" position and do not use the throttle lock.

Hold the saw firmly, press valve (D) for decompression and pull the starter rope.

STARTING A WARM ENGINE AFTER RE-FUELLING

In the fuel tank as run completely dry, proceed to start as with a cold engine.

USAGE

F

IMPORTANT

Before using a chain saw read the Operator's Manual and all safety precautions carefully.

FELLING TREES

• Make sure that there are no bystanders or animals in the work area.
• Study the direction of the fall of the tree and then plan your exit path away from the planned direction of fall.
• Don't fell trees when there is a strong wind.

1 Clear the tree base of interfering limbs and brush. Clean the work area from stones or other objects which could damage the chain. If the tree has large protruding roots, remove them before felling (see illustrations).

2 A) Cut a felling notch (A) of 45° on the side you want the tree to fall to a depth of about one third of the trunk diameter (d). Then make a felling cut (B) about 5 cm higher than the felling notch on the opposite side of the tree. Make sure that the felling cut does not go right through the trunk. A hinge (C) must always be left to provide control over the direction of the fall.

B) Use wedges to control the moment and direction of the fall.

3 When the tree starts to fall, walk away along your preplanned escape path.

CUTTING FALLEN TRUNKS

4 A) Limbing thick branches. For limbing and bucking leave the lower limbs to support the log off the ground.
B) Supported at one end only. Begin with a bottom cut made by the upper side of the bar (A); the depth of the cut should be about one third of the log diameter. Finnish with a top cut (B) meeting the first one. With this technique splitting, cracking can be avoided
C) Supported at both ends. Begin with a top cut about one third of the log diameter. Then finish with a bottom cut (B) meeting the first one. This technique avoids the risk of pinching the bar in the log.
D) If the log is supported along its whole length it may be cut normally from above. Take care not to touch the ground with the chain.

• When working on a slope always stand on the uphill.
• When cutting prepared timber, use clamps or chocks to secure work.
• Use extreme caution when cutting small size brush and saplings which may catch the chain and pull you off balance.

CARBURETTOR ADJUSTMENT

We suggest carburetor adjustments are made by an authorized servicing dealer.

The carburetor has three adjustment screws:

- L: The needle screw L governs the fuel flow at low speed and also the acceleration from low to full speed.

To set screw L: close screw L turning it clockwise without forcing.

Then open screw 1 full turn (counterclockwise).

If acceleration is not smooth, open another 1/8 turn to increase fuel flow.

• H: The needle screw H governs fuel flow at high speed (throttle valve fully open).

To set hi speed screw H: close screw H turning it clockwise without forcing.

Then open screw 1 full turn (counterclockwise).

If the engine speed is too high, open the screw about 1/8 turn (counterclockwise). Optimal adjustment is found between 1 and 1 1/4 turns.

- I: The I (IDLE) screw controls the throttle opening to govern idle speed (2800 min ^-1 ) adjust as necessary.

CAUTION: increased idle speed may cause chain movement. The carburetor is adjusted for normal operation during production. When considerable changes of altitude require a supplementary adjustment, contact an authorised service station which offers the latest in tools, parts and technical assistance.

ROUTINE MAINTENANCE

Ensure engine is always switched off before any kind of maintenance operation.

CHAIN: Check tension regularly. A new chain will require more frequent adjustment. Loosen retention nuts. Tighten chain (see assembly instructions). Tighten retention nuts and adjust.

1 BAR

- Clean the bar groove (K) and check the lubrication holes (L) in the bar to ensure that they are not clogged.

- Grease sprocket periodically. Rotate sprocket and repeat.

- Rotate bar periodically to maximise bar life.

2 AIR FILTER

- A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum r.p.m. and cause high fuel consumption.

- Remove cover.

- Wash filter in petrol (do not use fuel which is mixed with oil).

- The filter can also be cleaned with compressed air.

- Replace filter if damaged or if it does not seal tightly in the air box.

3 SPARK PLUG

Remove and clean the spark plug every 30 hours. Check the electrode gap (0,5/0,6 mm. - 0.025 inches).

- Replace spark plug about every 100 working hours or whenever it is extremely encrusted.

- Heavily encrusted electrodes can result from an incorrect carburetor setting or from wrong fuel mixture (too much oil in the fuel mix) or a poor quality of oil in the fuel mix. Check and correct.

4 OIL FILTER

The oil filter is on the end of the oil suction hose inside the oil tank.

To clean and replace the filter pull it out through the oil tank filter opening. Use a piece of bent wire or long forceps.

To remove deposits from the oil tank half-fill it with kerosene or petrol and shake thoroughly. Drain off and fill the tank with fresh saw chain oil.

Never use waste oil.

5 FUEL FILTER

To change fuel filter remove the tank cap and pull out the filter with a piece of bent wire or long forceps. Replace the filter as shown in the illustration and reposition it.

It is recommended to replace the fuel filter at least once a year.

CHAIN BRAKE

- WARNING: Contact your service dealer if anything appears wrong with your chain brake. Do not disassemble or manipulate the mechanism of the chain brake.

- Clean the brake mechanism periodically (without disassembling it) and control the wear of the band visually.

- PERIODICALLY: It is important to clean the saw thoroughly particularly around cylinder fins to avoid overheating of the engine.

- LONG STORAGE: Empty fuel and run engine until dry.

SAFETY CHAIN BRAKE

Your chain saw is fitted with a safety chainbrake designed to stop the chain in milliseconds in case of kickback. Always hold the saw firmly in both hands.

The chain brake does not provide a total protection if the machine is used without taking the necessary precautions and maintenances.

The chain brake is intended to engage automatically in case of kickback.

The chain brake can also be engaged manually by pushing the chain brake lever forwards. The manual use of the chain brake is recommended only at idle.

Always test the chain brake before using your saw. Do this by engaging the brake at idle (see below).

Always release the brake before starting.

Kickback may occur if the end of the bar (see illustrated angle) touches any solid object.

Never attempt to start a cut with the end of the bar.

Kickback is a violent upward and rearward movement of the bar and may cause you to lose control of the machine.

Therefore you should avoid starting a cut with this part of the bar. Always keep a firm grip on the saw with both hands because, in case of kickback, it is the contact of the left hand with the brake lever which will help to engage the brake.

CHAIN BRAKE TESTING:

1 The chain brake (A) is disengaged when brake lever is pulled back and locked(chain can move).

2 The chain brake (A) is engaged when brake lever is in the position (chain cannot rotate). The chain brake should snap into both positions. If strong resistance is felt or lever does not move into either position, DO NOT USE YOUR SAW. Take it immediately to an authorized servicing dealer.

3 CHAIN CATCHER

This unit is fitted with a chain catcher below the drive spocket. This is intended to stop the rearward movement of the chain in case of breakage or if it should come out of the bar. It should never be removed.

CHAIN SHARPENING

1 Chain cutter teeth can be sharpened with a round file, as follows:

CHAIN FILE

MP 370 GLX 5/32"

PM 320 GX 3/16"

The exact chain type is marked on the bottom half of the drive link which runs inside the bar groove.

Filing can be made easier by also using a file holder.

The chain can remain fitted on the bar during sharpening.

Before commencing, the chain should be tensioned correctly and the chain brake should be activated to prevent the chain from moving.

2 To obtain a correct sharpening the file must be carefully held to maintain 3 basic angles:

• "A" Top angle 30° - 35°
• “B” External, side angle 85° - 90°
• "C" Internal, side angle 60°

File in one direction only, from the “inside” of the cutter tooth towards the “outside”.

Do not allow the file to touch the chain as you bring it back to re-position it. Each cutter tooth should be filed with the same number of strokes.

3 The file should be held horizontally to the cutter tooth being sharpened.
4 Best results to obtain a precise sideways angle can be obtained by holding the file so that it rises 0,5 mm above the top face of the cutter tooth.

5 DEPTH GAUGE

Correct depth gauge height is vital to ensure maximum chain life and cutting efficiency.

The height of the depth gauge should be lowered as the cutter tooth is filed back; this height should be checked every 4 or 5 sharpenings.

The best way to do this is to use a flat file and a depth gauge tool.

The correct setting is 0.65 mm below the top edge of the cutter tooth.

The cutter tooth depth gauge should then be rounded (D).
