Frequently Asked Questions - CG 27EBSP(SL) HiKOKI

How to start the engine?

Set the ignition switch away from stop. Push the priming bulb about ten times. Set the choke lever to START (closed) position. Pull the recoil starter briskly. When the engine tries to start, return choke lever to RUN (open) position and pull again. Allow 2-3 minutes warm-up.

What fuel mixture should I use?

Use unleaded gasoline (89 octane) mixed with a quality 2-cycle oil at a ratio of 25:1 to 50:1. For best results, use genuine HiKOKI oil or JASO FC/ISO EGC grade oil. Do not use multi-grade or water-cooling type oil.

How to adjust the cutting line length?

With the engine running at low rpm (not over 4500 min⁻¹), tap the head on the ground. Each tap extends the line about 3 cm. Also, you can manually extend the line when the engine is stopped. Adjust to a length of 11–14 cm on each side.

What should I do if the engine does not start?

Check that the fuel tank has fresh fuel mixture. If the spark plug is wet from flooding, disconnect it and dry it, then pull the starter several times with the choke in RUN position. Clean or replace the spark plug, and ensure the fuel filter and lines are clear. If problems persist, contact HiKOKI service.

How to maintain the air filter?

Clean the air filter daily or more often in dusty conditions. Open the air filter cover, remove the filter, and rinse it in warm soapy water. Ensure it is completely dry before reassembly. Replace the filter regularly if it cannot be cleaned thoroughly.

How to replace the nylon cutting line?

Remove the case by pushing the locking tabs inward. Take out the reel and discard remaining line. Fold a new 2.4 mm line unevenly in half, hook the U-shaped end into the reel groove, and wind both halves in the same direction on their own side of the partition. Push each line into the stopper holes, leaving 10 cm ends. Insert ends through the cord guide, place reel in case, and secure the cover until it clicks.

What safety precautions should I take?

Always wear eye, head, and ear protection, heavy long pants, non-slip boots, and gloves. Keep all bystanders at least 15 m away. Inspect the unit for damage before use. Never operate under the influence of alcohol or drugs. Hold the unit firmly with both hands and keep the engine on your right side.

How to install a metal cutting blade?

Ensure the blade is not cracked or damaged. Press the stopper pin to lock the cutter holder. Place the blade with cutting edges facing the correct direction. Use the cutter holder cap (concave side upward) and tighten the fixing nut counter-clockwise (left-hand thread) to a torque of 12–16 N·m. Wear gloves when handling the blade.

How to adjust the idle speed?

With the engine running, turn the idle speed adjustment screw (T) clockwise until the cutting attachment starts to rotate, then turn it counter-clockwise until it stops. The correct idle speed is when the engine runs smoothly and the attachment does not rotate. Standard idle rpm is 2800–3200 min⁻¹.

What is the correct spark plug gap?

The correct electrode gap is 0.6 mm. If the gap is incorrect, adjust it carefully. Replace the spark plug after about 100 operation hours or if electrodes are badly eroded. Use a resistor spark plug if originally equipped.

Idle speed adjustment (T)

Check that the air filter is clean. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate. n is called blade

If the cutting attachment still rotates after idle speed adjustment, contact HiKOKI Authorized Service Centers.

NOTE

Standard Idle rpm is 2800 - 3200 min ^-1 .

WARNING

When the engine is idling the cutting attachment must under no circumstances rotate.

Air fi Iter (Fig. 29)

The air filter must be cleaned from dust and dirt in order to avoid:

○ Carburetor malfunctions
○ Starting problems
○ Engine power reduction
○ Unnecessary wear on the engine parts
○ Abnormal fuel consumption

Clean the air filter daily or more often if working in exceptionally dusty areas.

Cleaning the air fi Iter

Open the air filter cover and the filter (28). Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be replaced.

Fuel fi Iter (Fig. 30)

Drain all fuel from fuel tank and pull fuel filter line from tank. Pull filter element out of holder assembly and rinse element in warm water with detergent.

Rinse thoroughly until all traces of detergent are eliminated. Squeeze, do not wring, away excess water and allow element to air dry.

NOTE

If element is hard due to excessive dirt buildup, replace it.

Spark plug (Fig. 31)

The spark plug condition is influenced by:

○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi Iter
○ Hard running conditions (such as cold weather)

These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.6 mm. The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

NOTE

In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement.

Angle transmission (Fig. 32)

Check angle transmission or angle gear for grease level about every 50 hours of operation by removing the grease filler plug on the side of angle transmission.

If no grease can be seen on the flanks of the gears, fill the transmission with quality lithium based multipurpose grease up to 3/4. Do not completely fill the transmission.

Semi-auto cutting head

Nylon line replacement

(1) Remove the case (29) by firmly pushing inward the locking tabs with your thumbs as shown in Fig. 33.
(2) After removing the case, take out the reel and discard the remaining line.
(3) Fold the new nylon line unevenly in half as shown in picture. Hook the U-shaped end of the nylon line into the groove (30) on the center partition of the reel.

One side of the cord should be about 10 cm longer other side.

Wind both halves of the line on the reel in the same directic keeping each half of the line on its own side of the partition. (Fig. 34)

(4) Push each line into the stopper holes (31), leaving the loose ends approx. 10 cm in length. (Fig. 35)
(5) Insert both loose ends of the line through the cord guide (32) when placing the reel in the case. (Fig. 36)

NOTE

When placing a reel in the case, try to line up the stopper holes (31) with the cord guide (32) for easier line release later.

(6) Place the cover over the case so that the cap locking tabs (33) on the case meet the long holes (34) on the cover. Then push the case securely until it clicks into place. (Fig. 37)

(7) The initial cutting line length should be approx. 11–14 cm and should be equal on both sides. (Fig. 38)

Blade (Fig. 39)

WARNING

Wear protective gloves when handling or performing maintenance on the blade.

○ Use a sharp blade. A dull blade is more likely to snag and thrust. Replace the fastening nut if it is damaged and hard to tighten.
○ When replacing blade, purchase one recommended by HiKOKI, with a 25.4 mm (one inch) ft tting hole.
○ In the case of a 3 tooth blade (35), it can be used on either side.
○ Use the correct blade for the type of work.
○ When replacing blades, use appropriate tools.
When cutting edges become dull, re-sharpen or file as shown in the illustration. Incorrect sharpening may cause excessive vibration.
○ Discard blades that are bent, warped, cracked, broken or damaged in any way.

NOTE

When sharpening blade it is important to maintain an original shape of radius at the base of the tooth to avoid cracking.

Maintenance schedule

Below you will find some general maintenance instructions. For further information please contact HiKOKI Authorized Service Centers.

Daily maintenance

○ Clean the exterior of the unit.
○ Check that the harness is undamaged.
○ Check the cutting attachment guard for damage or cracks. Change the guard in case of impacts or cracks.
☐ Check that the cutting attachment is properly centred, sharp, and without cracks. An off-centre cutting attachment induces heavy vibrations that may damage the unit.
○ Check that the cutting attachment nut is sufficiently tightened.
○ Make sure that the blade transport guard is undamaged and that it can be securely fitted.
○ Check that nuts and screws are sufficiently tightened.
○ Check that the unit is undamaged and free of defects.

Weekly maintenance

○ Check the starter, especially the cord and return spring.
○ Clean the exterior of the spark plug.
○ Remove it and check the electrode gap. Adjust it to 0.6 mm, or change the spark plug.
○ Check that the angle gear is filled with grease up to 3/4.
○ Clean the air filter.

Monthly maintenance

○ Rinse the fuel tank with gasoline.
○ Clean the exterior of the carburetor and the space around it.
○ Clean the fan and the space around it.
