Maintaining the saw chain
The Saw Chain (24) must be sharpened regularly, and adjusted to the manufacturer's requirements. Have
the Saw Chain sharpened by a qualified professional
Replacement Saw Chains are available from your GMC stockist or from toolsparesonline.com
Maintaining the air cleaner
WARNING: Never run this chainsaw without the air cleaner fitted, as this will lead to rapid wear of internal
components, cause permanent engine damage, and shorten the service life of the chainsaw.
1. Turn the Airbox Knob (13) anticlockwise and remove the Airbox Cover (12)
2. Remove the air filter element (Image C)
Note: The Air Filter Element (38) can be split in half, if required, for cleaning.
3. Wipe off any dirt deposits from the air filter frame; thoroughly remove all deposits from the filter mesh using
GB
a soft brush. If compressed air is available, blow mesh from the inside
4. Use a mild detergent solution or another suitable solvent to remove oil deposits. Dry the Air Filter Element
thoroughly
5. Refit the air filter element and Airbox Cover to the chainsaw, and tighten the Airbox Knob in a clockwise
direction until hand-tight
Maintaining the fuel filter
The fuel filter is located on the fuel suction pipe inside the Fuel Tank (20)
Clean the mesh filter and rinse with fresh petrol. Replace if necessary
Maintaining the oil filter
The chain oil filter is located on the suction pipe inside the Chain Oil Reservoir (7)
Clean the mesh filter and rinse with fresh petrol. Replace if necessary
Maintaining the spark plug
WARNING: NEVER test the ignition system with an unseated spark plug or the ignition wire removed from the
spark plug. Uncontained sparking may ignite fuel and cause a fire.
Note: To ensure proper engine operation, the Spark Plug must be kept free of deposits, with the electrode
properly gapped.
WARNING: Switch off the Ignition Switch (14) and wait until the engine has cooled completely, before attempting
to remove the Spark Plug (40).
1. Turn the Airbox Knob (13) anticlockwise, remove the Airbox Cover (12) and the Air Filter Element (38)
2. Pull the Ignition Lead (40) off the top of the Spark Plug
3. Clean any dirt from the Ignition Lead or the top of the Spark Plug
4. Use the included Spark Plug Combi Tool (1) to loosen the Spark Plug by turning it anticlockwise. Once
loosened, remove the Spark Plug by hand
5. Visually inspect the Spark Plug. Discard if the ceramic insulation is cracked, or if any other damage is
detected
6. If any deposits are visible around the electrode area, brush off with a brass wire spark plug brush (not
included)
WARNING: Never clean spark plugs by sandblasting.
Note: If damage to the electrodes becomes visible during or after cleaning, the Spark Plug needs to be replaced
(see 'Specification' for compatible types).
7. Check electrode gap with a feeler gauge or specialised spark plug gap tool (both not included), and adjust if
necessary (Fig XIII)
8. Reinstall the Spark Plug by screwing it into the engine by hand, and tightening it with the Spark Plug Combi
Tool
Note: When fitting a new, previously unused spark plug, it should be seated by hand and then tightened about
1/2 a turn with a wrench to compress its washer. A previously fitted spark plug only requires a 1/8 to 1/4 turn,
after being seated by hand. The use of a torque wrench to set spark plugs is recommended. The correct torque
for this device is 20Nm.
WARNING: The Spark Plug must be securely tightened. An improperly tightened spark plug can become very
hot and damage the chainsaw.
WARNING: Never fit a spark plug with an improper heat range (see 'Specification' for compatible types).
9. Push fit the Ignition Lead, refit the Air Filter Element and Airbox Cover
Adjusting the carburettor
Note: This chainsaw has been fitted with a factory pre-adjusted carburettor, which should need no regular
re-adjustment, though carburettor settings may need fine tuning or resetting due to changes in operational
conditions (e.g. altitude use).
Note: The Guide Bar (22) and Saw Chain (24) need to be installed and properly adjusted prior to adjusting the
carburettor.
1. Ensure the Fuel Tank (20) is filled with fresh fuel
2. With the engine NOT running, gently turn both 'H' Screw (44) and 'L' Screw (42), in a clockwise direction,
until they stop
WARNING: NEVER force the carburettor adjustment screws.
3. Set the screws back the initial number of turns: 'H' Screw: 1-3/8 turns, 'L' Screw 1-1/4 turns
4. Start the engine (see 'Starting and stopping the engine'), and allow it to warm up at half throttle
5. Slowly turn the 'L' screw clockwise, until you find the position of maximum idling speed, then turn back ¼
turn anticlockwise
6. Slowly turn the 'T' Idle Adjusting Screw (43) anticlockwise so the Saw Chain does not move. Turn clockwise,
should idling speed be too low
7. Make test cuts and adjust 'H' Screw until the best cutting performance is reached (NOT the maximum chain
speed)
Storage
Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Recycling and disposal of petrol engine powered tools, fuel and oil
Tools powered by petrol-based internal combustion engines must not be disposed of with household
waste. Such tools should be taken to your local recycling centre and disposed of according to current
environmental protection requirements in your country.
Petrol, oil and petrol-oil-mixtures are hazardous waste and have to be treated as such. Oil and fuel must
not be disposed of with household waste. Improper disposal may be regarded a criminal offence in your
country. Contact your local authority or dealer for correct disposal procedures for oil and old fuels.
