Maintenance and Service
Maintenance and Cleaning
Before any work on the product, disconnect supply
u
cord from the mains.
– Always fit the chain guard (26) on the chain bar (17)
when the chain saw is not being used to prevent injury.
– For safe and proper working, always keep the power tool
and its ventilation slots clean.
– Do not use water, solvents or polishes.
– Clean the chain and chain bar before storing the product
for an extended period of time to prevent the parts from
seizing.
– Remove the SDS cover (25), chain bar (17) and saw
chain (18) and clean these parts with a brush to remove
oil, sap and dust residue, especially from the saw blade
groove.
– Use a clean cloth to carefully remove debris from the oil
outlet (7) and drive sprocket (3). Make sure that no
debris enters the oil outlet (7), as this can cause block-
ages and lubrication problems.
– Carry out the required maintenance before use.
– Regularly check the chain saw for obvious defects such as
loose, dislodged or damaged saw chain and chain bar,
loose fixings and worn or damaged components.
– Do not modify this product. Unauthorized modifications
may impair the safety of your product and may result in
increased noise and vibration.

– Always empty the oil reservoir before storage and refill it
before use.
– Store the chain saw in a secure, dry place, out of the
reach of children.
– Do not place other objects on the chain saw.
Replacing and Sharpening the Saw Chain
– The saw chain can become blunt through prolonged use
or when coming into contact with objects other than
wood.
– A sharp saw chain is required for optimum performance
and safety.
– Never sharpen the saw chain yourself unless you have ex-
perience with it.
– Replace the saw chain with the Bosch saw chain access-
ory or have the saw chain professionally resharpened.
Replacing the Chain Bar
Only replace the chain bar if you fully understand the
u
product and the instructions, otherwise please con-
tact the Bosch Service Centre.
– If the chain bar is worn, you can mount it upside down to
extend its life, or you can replace it.
– Use a hex key to loosen the screw between the chain
bar (17) and the affixed tensioning wheel (19).
– Once you have flipped or replaced the chain bar, reattach
the affixed tensioning wheel (19).
Note: Tighten by hand until slight resistance, then add 1/8
extra turn for the required fixing. Overtightening can cause
the chain bar to pinch and restrict the path of the rotating
saw chain.
