4. Use the included Chainsaw Combination Wrench (26) 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 you
detect any other damage
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
8. Reinstall the Spark Plug by screwing it into the engine by hand, and tightening it with
the spark plug wrench
Note: When fitting a new, previously unused spark plug, it should be seated by hand and
then tightened about 1/2 turn with a wrench, to compress its washer. A previously fitted
spark plug only requires 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 Spark Plug Cap, refit the Air Cleaner and Air Cleaner 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 (1) and Saw Chain (2) need to be installed and properly adjusted, prior
to adjusting the carburettor.
1. Ensure the Fuel Tank (9) is filled with fresh fuel
2. With the engine NOT running, gently turn both ‘H’ Screw (33) and ‘L’ Screw (34), 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 let it 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 (32) 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 carefully in a secure, dry place out of the reach of children
• Fit the Safety Cover (23) over the Guide Bar (1) and Saw Chain (2) for storage
Preparation for long-term storage
• Whenever the chainsaw is out of use for an extended period of time, proceed as follows:
1. Give the unit an overall cleaning and a thorough check
2. Clean the Air Cleaner (20)
3. Drain the fuel system
4. Remove the Spark Plug (22), fill about a spoonful of 2-stroke oil into the cylinder
through the spark plug hole, and pull the Recoil Starter (5) gently two to three times
to distribute the oil evenly. Replace the Spark Plug
5. Slowly pull the Recoil Starter just until resistance is felt. At this point, the piston is
coming up on its compression stroke, and both the intake and exhaust valves are
closed. Storing the engine in this position will help prevent internal corrosion
6. Protect all metal parts from corrosion by coating them with oil or a machinery
preservative
Adjusting chain tension
WARNING: ALWAYS wear cut-proof gloves when touching the saw chain, to avoid injury.
1. Loosen the Guide Bar Nuts (17) using the supplied Chainsaw Combination Wrench
(26)
2. Use the screwdriver end of the Chainsaw Combination Wrench to adjust the Chain
Tensioner Screw (31):
• turn clockwise to increase chain tension
• turn anticlockwise to decrease chain tension
3. Tighten the Guide Bar Nuts securely (12-15Nm)
4. Check chain tension as described in ‘Checking the chain tension’. Start over from
step 1, should you need to correct adjustments
Maintaining the chain brake
• The chain brake is an important safety feature of this chainsaw. It is designed to reduce
the risk of kickback and user injury. In order for it to properly perform its function, it
must be maintained regularly. Like an automobile brake, the chain brake incurs wear
with each operation. Excessive wear will reduce the chain brake’s effectiveness, and
can render it inoperable.
• Return the chainsaw to your authorised Silverline service centre for maintenance at
least once a year (more often of the device is frequently used), if there is a change in the
operating characteristics of the chain brake, or if the saw fails the pre-operational chain
brake test (see ‘Testing the chain brake)
Maintaining the chain drive
• Regularly inspect the Sprocket (29) for wear and damage
• Return the chainsaw to an authorised Silverline service centre, to replace a worn or
damaged Sprocket
WARNING: NEVER fit a new Saw Chain (2) to a worn Sprocket (29), or a worn Saw Chain
to a new Sprocket.
Maintaining the saw chain
• The Saw Chain (2) must be sharpened regularly, and adjusted to the manufacturer’s
requirements. Have your Saw Chain sharpened by a qualified professional
• Replacement Saw Chains are available from your Silverline stockist or from
toolsparesonline.com
Maintaining the air cleaner
WARNING: Never run this chainsaw without the air cleaner fitted, as this would lead to
rapid wear of internal components, causing permanent engine damage and shorten the
service life of this chainsaw.
1. Turn the Cover Screw (7) anticlockwise and remove the Air Cleaner Cover (6)
2. Remove the Air Cleaner (20)
Note: The Air Cleaner (20) can be split in half, should this be required for cleaning.
3. Wipe off any dirt deposits from the Air Cleaner frame; thoroughly remove all deposits
from the filter mesh using 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
Air Cleaner thoroughly
5. Refit the Air Cleaner and Air Cleaner Cover to the chainsaw, and tighten the Cover
Screw 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 (9)
• 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 (15)
• 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 (22). 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 Engine Switch (14) and wait
until the engine has cooled completely, before attempting
to remove the Spark Plug.
1. Turn the Cover Screw (7) anticlockwise, remove
the Air Cleaner Cover (6) and the Air Cleaner (20)
2. Pull the Spark Plug Cap (21) off the top of the
Spark Plug
3. Clean any dirt from the Spark Plug Cap or the top
of the Spark Plug
