4. Operate the throttle trigger a few times to make sure that it works correctly.

5. Adjust the cable adjuster sleeve so the stop on the carburetor throttle cam just contacts the throttle stop and the cable position keep 1-2mm play between cable lug and slotted fittings when the throttle trigger is fully depressed. [#26-3]

6. When the throttle cable is adjusted correctly, tighten the lock-nut.

7. Plug the stop switch wires into the matching connectors from the engine.

NOTE: that wire polarity is not important.

1. Lap and fix the stop switch wires and connectors with clamp. [#26-4]
2. Reinstall the air filter cover and tighten the knob.

Guide bar and saw chain installation

CAUTION

• In order to prevent cuts, be sure to wear gloves when handling the guide bar and saw chain.
• Maintain the tension of the saw chain properly at all times.
• If not enough tension is applied to the saw chain it can easily be dislodged when the saw chain is in motion.

• If too much tension is applied to the guide bar, saw chain and clutch may wear prematurely as a result.

• Slot the saw chain in the groove of the guide bar, ensuring that the cutter section of the saw chain is facing the front. [#27-1]

• Engage the saw chain into the sprocket.
• Insert the groove of the guide bar into the pruner's main unit and adjust the regulating screw to ensure that the adjuster is inserted in the circular hole of the guide bar. [#27-2]
• Put the chain cover on and temporarily screw it in place using a nut, to the extent that the guide bar can be moved.

1. Lift up the leading edge of the guide bar and using a screw driver turn the regulating screw clockwise to tighten the saw chain until the saw chain slightly touches the lower side of the guide bar. [#28-1]
2. Securely tighten the nut on the chain cover, using the box spanner, provided as an accessory with the product. [#28-2]
3. Verify that the saw chain on the central section of the guide bar can be lifted by the fingers 3 to 4 mm off the guide bar. [#28-3]

Nut Tuerca Écrou

[#28-3]

Installing Shaft and Gearcase

Attach the shaft assembly to the Pruner gearcase assembly. [#29-1]

NOTE: Insert the shaft assembly into the gearcase, turning the drive shaft to get it meshing correctly the spline. Align the locating hole and install the locating screw through the side of the gearcase. Then tighten the clamping screw.

Attaching Strap

Snap the strap hook into the ring on the shaft assembly. To detach the strap quickly from the Pruner, pull upward on the red band. [#29-2]

1. Remove the oil tank cap and pour the chain oil (SAE #10W-30) into the oil tank.
2. Once the oil has been poured into the oil tank, tighten the oil tank cap to securely close the tank.

DANGER

- Ensure that the guide bar and saw chain are installed on the pruner before verifying the discharging rate of the chain oil. The rotator will be exposed and therefore dangerous if the guide bar and the saw chain are not installed on the pruner.

CAUTION

• It may take some time before the oil begins to discharge once the oil has been added to a new product or when oil has been added to an empty tank. Do not turn the pruner on at a high speed in such circumstances.
• When a new chain is to be used, immerse the chain in chain oil for some time prior to installing it on the pruner, or pour the oil directly on to the chain and the guide bar, after installing it on the pruner. If they are not properly lubricated with oil the pruner may seize.

Antes de Utilizar

Aceite de la cadena

2) Regulating oil discharging rate

The regulating screw has three positions, Minimum, Intermediate and Maximum, only.

The regulating screw is set to Intermediate at the time of shipping. It is recommended that the product be used with this setting for ordinary use.

- Increase the discharging rate when cutting hard branches or branches with a lot of resin (pitch), or when the viscosity of the oil is high during winter.

1. Insert a minus screw driver into the regulating screw at the bottom of the main unit. [#31-1]
2. When applying pressure with the minus screw driver, turn the screw to the right (clockwise) to reduce the discharging rate and to the left (counter-clockwise) to increase the discharging rate. [#31-2]
3. Turn the engine on and turn the saw chain, with the guide bar facing the ground or tree. Oil will attach to the ground or tree, if the oil is discharging.

- Using the pruner with a saw chain too loose may result in the saw chain becoming dislodged and could cause an accident. Please be sure to check the tension of the saw chain before starting any work.

ADVERTENCIA

- In certain conditions gasoline is extremely flammable and highly explosive.

WHAT CAN HAPPEN

- A fire or explosion from gasoline can burn you, others, and cause property damage.

HOW TO AVOID THE HAZARD

• Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is could. Wipe up any gasoline that spills.
• Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2in. (6mm to 13mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
• Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.
• Store gasoline in an approved container and keep it out of the reach of children.

• Never buy more than a 30-day supply of gasoline.

• Do not smoke near fuel.

• Mix and pour fuel outdoors and where there are no sparks or flames.

WARNING

POTENTIAL HAZARD

- Gasoline contains gasses that can build up pressure inside a gas tank.

WHAT CAN HAPPEN

- Fuel can be sprayed on you when removing gas cap.

HOW TO AVOID THE HAZARD

- Remove fuel cap slowly to avoid injury from fuel spray.

1. Always shut off the engine before refueling. Never remove the fuel tank cap while the engine is running or right after just stopping the engine.
2. Always open the fuel tank cap slowly to release any possible overpressure inside the tank.

Recommended Oil Type

Only use a two-stroke engine oil formulated for use in high-performance, air-cooled two-stroke engines. MARUYAMA brand two-stroke oil is formulated for use in high-performance, air-cooled two-stroke engines.

IMPORTANT: Do not use National Marine Manufacturer's Association (NMMA) or BIA certified oils. This type of two-stroke engine oil does not have the proper additives for air cooled, two-stroke engines and can cause engine damage.

Do not use automotive motor oil. This type of oil does not have the proper additives for air-cooled, two-stroke engines and can cause engine damage.

Recommended Fuel Type

Use clean, fresh lead-free gasoline, including oxygenated or reformulated gasoline, with an octane rating of 89 or higher. To ensure freshness, purchase only the quantity of gasoline that can be used in 30 days.

Use of lead-free gasoline results in fewer combustion chamber deposits and longer spark plug life. Use of premium grade fuel is not necessary or recommended.

Use of Fuel Additives

IMPORTANT: NEVER USE ALCOHOL, GASOHOL CONTAINING MORE THAN 10% ALCOHOL BECAUSE ENGINE FUEL SYSTEM DAMAGE COULD RESULT.

DO NOT USE FUEL ADDITIVES OTHER THAN THOSE MANUFACTURED FOR FUEL STABILIZATION DURING STORAGE SUCH AS MARUYAMA'S STABILIZER/CONDITIONER OR A SIMILAR PRODUCT. MARUYAMA'S STABILIZER/CONDITIONER IS A PETROLEUM DISTILLATE BASED CONDITIONER/STABILIZER.

MARUYAMA DOES NOT RECOMMEND STABILIZERS WITH AN ALCOHOL BASE SUCH AS ETHANOL, METHANOL OR ISOPROPYL. ADDITIVES SHOULD NOT BE USED TO TRY TO ENHANCE THE POWER OR PERFORMANCE OF MACHINE.

Mixing Gasoline and Oil

IMPORTANT: The engine used on this Pruner is of a two-stroke design. The internal moving parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder wall contact surfaces, require oil mixed with the gasoline for lubrication.

Failure to add oil to the gasoline or failure to mix oil with the gasoline at the appropriate ratio will cause major engine damage which will void your warranty.

For your fuel premix, use MARUYAMA Premium two-stroke Oil Mix, or equivalent ISOL- EGD & JASO FD oil with a minimum 89 octane high Quality gasoline. MARUYAMA two-stroke oil is specially formulated to meet the requirements of high-performance, low-emission air-cooled two-stroke engines. Use of other oils may lead to service issues which may Not be covered by your warranty.

Fuel Mixture

The fuel: oil ratio is 50 parts gasoline to 1 part oil or 50:1. [#34-1]

Note: Never use a mixing ratio less than 50:1 regardless of the oil package mixing instructions. Ratios less than 50:1, (for example, 60:1, 80:1, 100:1), reduce the amount of lubrication to the internal moving parts of the engine and can cause damage.

Fuel Mixture Chart

Refer to the chart above. [#34-2]

Mixing Instructions

IMPORTANT: Never mix gasoline and oil directly in the Pruner fuel tank.

1. Always mix fuel and oil in a clean container approved for gasoline.
2. Mark the container to identify it as fuel mix for the Pruner.
3. Use regular unleaded gasoline and fill the container with half the required amount of gasoline.
4. Pour the correct amount of oil into the container then add the remaining amount of gasoline.
5. Close the container tightly and shake it momentarily to evenly mix the oil and the gasoline before filling the fuel tank on the Pruner.
6. When refilling the Pruner fuel tank, clean around the fuel tank cap to prevent dirt and debris from entering the tank during cap removal.
7. Always shake the premix fuel container momentarily before filling the fuel tank.
8. Always use a spout or funnel when fueling to reduce fuel spillage.
9. Fill the tank only to within 1/4-1/2 in. (6mm-13mm) from the top of the tank. Avoid filling to the top of the tank filler neck.

Starting and Stopping

Before Starting The Engine

1. Fill the fuel tank as instructed in the Before Operation section of this manual (page 30).
2. Rest the Pruner on the ground.
3. Make sure the cutting attachment is clear of any broken glass, nails, wire, rocks or other debris.

2. If you did not change the control lever position, engine speed become to the original adjusted speed when grasp the throttle lever again.

• Do not stand immediately below the branch that is to be cut. The branch may fall directly below and the branch may also bounce of f other branches or the ground in an unexpected direction and cause injury to the worker.
• Do not allow anyone to enter within a 15 meter radius.
• The Pruner is not insulated to prevent electric shock. Keep it away from any power lines with at least 15 meters when working, as there is threat of electrocution.

Working position

1. Choose a working position where the inclination of the pole remains at 60 degrees or less.
2. Start cutting from the lower branches first so that the branches will fall off easily when cut.
3. The cut branches may fall towards the worker, so be sure to select a location that enables a stable footing and provides an easy escape in the case of an emergency.

WARNING

Wear a hat or helmet, protective glasses, gloves and ear plugs while working.

Furthermore, wear a dust mask whenever a lot of pollen or chipping powder is expected, which may be harmful for the health.

PELIGRO

Adjusting length of shaft assembly [#40-1]

WARNING

• Always stop the engine and set the guide bar cover when adjusting the length of the shaft assembly.

1. First of all, stop the engine then set the guide bar cover.
2. Loosen the clamping knob before adjusting the length of the shaft assembly. Be care falling down the clamping knob by over loosing.
3. Pull out or depress the shaft assembly from the slide holder for adjusting the shaft assembly length.
4. After adjusting the length, tighten the clamping knob firmly.

Cutting wood [#40-2]

1. Turn the pruner on full throttle and press the saw chain lightly against the wood to cut.
2. The cutting capacity is reduced when the engine revolution is slowed down and the saw chain is pressed hard against the wood.

IMPORTANT:

• Pressing the saw chain hard against the wood not only tires the operator quicker but also quickens the wear of the saw chain and guide bar.
• If wood cannot be cut without pressing the saw chain hard against it, this indicates that the saw chain is becoming dull. In such cases, either sharpen the saw chain or replace it with a new chain.

Pruning thick branches

Attempting to cut a thick branch in one go often results in the guide bar jamming in the branch or otherwise encountering difficulties in cutting. The method described below makes cutting thick branches easier:

1. First of all, cut a section slightly away and on the lower side of the desired area of the branch to be cut.
2. Then, start cutting from the upper side of the branch.
3. Thereafter, cut into the lower side where the desired area of branch is to be cut.
4. Finally, cut through from the upper side where the branch is to be cut, cutting the branch off.

IMPORTANT: If the guide bar or saw chain jams into the branch, do not force it. Widen the cut using a wedge to remove the pruner and try cutting it again. Forcing the pruner may damage the main unit of the pruner and cause a malfunction of the pruner.

Saw chain tension adjustments

WARNING

• When using the pruner be sure to turn the engine off before making any inspections or any adjustments.

• Do not make any adjustments when the guide bar or saw chain is still hot immediately after using the pruner. Wait until it has cooled before making any adjustments.

• Turn the nut on the chain cover once to loosen it.

• Lift up the leading edge of the guide bar and turn the regulating screw to tighten the saw chain. Turning the screw clockwise tightens the saw chain, whereas turning it counter-clockwise looses the saw chain.
• Securely tighten the nut on the chain cover.
• Verify that the saw chain on the central section of the guide bar can be lifted with fingers 3 to 4 mm off the guide bar.

IMPORTANT: To detach the strap quickly from the Pruner, pull upward on the red band.

Maintenance, replacement or repair of emission control devices and systems may be performed by any repair establishment or individual; however, warranty repairs must be performed by a dealer or service center authorized by MARUYAMA Manufacturing Company, Inc.

The use of parts that are not equivalent in performance and durability to authorized parts may impair the effectiveness of the emission control system and may have a bearing on the outcome of a warranty claim.

Maintenance on today's low-emission engines is even more critical for longest life and best performance. Particularly critical are air and fuel filters, spark plug heat range, cooling air intake area and proper gaps of coil and plug.

Idle Speed Adjustment

This Pruner is equipped with non-adjustable fuel mixture carburetor. The engine idle speed is the only adjustment for the operator.

WARNING

2. Reinstall the cylinder cover and the air filter cover.

Sharpening saw chain

Whenever wood chips become small and fine or the wood cannot be cut without pressing the pruner hard against it, then it may be necessary to sharpen the saw chain.

1. Tighten the saw chain slightly firmer than usual then secure the pruner's main unit.
2. Place a file with a 4.0mm (5/32 in.) diameter against the cutter and extend 1/5 of it beyond the cutter.

3. Press the file against the cutter at its base in a 30-degree angle from the vertical line and move the file straight ahead from the inner side to the outer side of the cutter. [#49-1]

4. Shift the file so that it remains in a 90-degree angle against the guide bar. [#49-2]

5. Once one side of the cutter is sharpened, sharpen the other side of the cutter. Be sure to keep the length and angle uniform throughout. [#49-3, #49-4]

IMPORTANT:

• The efficiency of this work greatly impacts the sharpness of the cutter. It is recommended that sharpening be performed often.
• Be sure to use an appropriate file for sharpening the saw chain cutters.

Adjusting depth gauge [#50-1]

The depth gauge determines how deep the cutter cuts into the wood.

1. When the cutter lengths become shorter due to sharpening, the depth gauge must also be cut back.
2. Cut down the depth gauge using a flat file in a way that the depth gauge is positioned 0.64mm (0.025in.) lower than the leading edge of the cutter.
3. Once cut back, grind the tip of the depth gauge round.

IMPORTANT: Be sure that the depth gauge is not cut back too far, as doing so will result in a faster deterioration of the cutter.

Guide bar care [#50-2]

1. When work using the pruner is finished for the day, remove the guide bar and saw chain from the pruner.
2. Remove any wood chips or other particles attached to the groove of the guide bar or in the oil hole. Be particularly certain that no particles are clogging the oil hole.
3. Remove wood chips and other particles around the oil discharge hole and around the sprocket on the main unit of the pruner.

IMPORTANT:

• When installing the guide bar, occasionally switch it to the top and bottom to prevent uneven wear and to extend the life of the guide bar.
• If the oil discharge hole becomes clogged by wood chips or other particles the pruner could seize up.

Inspection of sprocket [#51-1]

1. Inspect the sprocket to ensure that it is not worn out and that the snap ring is surely attached..
2. If the sprocket is worn by 0,3mm or more as shown, replace the sprocket. Continuing to use the pruner with the sprocket in such a condition will shorten the life of the saw chain.

Gearcase [#51-2]

1. Remove the gearcase from the shaft assembly.
2. Remove the grease plug and prepare some lithium-type grease.
3. Inject enough grease (about 10g) so that some of it spills out through the spline hole, to which the drive shaft is inserted.
