– Guide the file as shown in the figure. (Fig. 38)
– The file can be guided more easily if a file holder
(optional accessory) is employed. The file holder has
markings for the correct sharpening angle of 30° (align
the markings parallel to the saw chain) and limits the
depth of penetration (to 4/5 of the file diameter).
(Fig. 39)
– After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional
accessory). (Fig. 40)
– Remove any projecting material, however small, with a
special flat file (optional accessory).
– Round off the front of the depth gauge again.
Cleaning the guide bar and lubricating the
return sprocket
CAUTION:
• Always wear safety gloves for this task. Burrs present a
risk of injury.
Check the running surfaces of the bar regularly for
damage. Clean using a suitable tool, and remove burrs if
necessary. (Fig. 41)
If the chain saw receives frequent use, lubricate the return
sprocket bearing at least once a week. Before adding new
fresh grease, carefully clean the 2 mm hole on the tip of
the guide bar, then force a small quantity of multi-purpose
grease (optional accessory) into the hole.
Cleaning the oil guide (Fig. 42)
– Clean the oil guide groove and the oil feed hole in the
bar at regular intervals.
New saw chains
Use two or three saw chains alternately, so that the saw
chain, sprocket and running surfaces of the bar wear
evenly.
Turn the bar over when changing the chain so that the bar
groove wears evenly.
CAUTION:
• Only use chains and bars which are approved for this
model of saw (refer to "SPECIFICATIONS").
Before fitting a new saw chain, check the condition of the
sprocket. (Fig. 43)
CAUTION:
• A worn sprocket damages a new saw chain. Have the
sprocket replaced in this case.
Always fit a new locking ring when replacing the sprocket.
Maintaining the chain and run-down
brakes
The braking systems are very important safety features.
Like any other component of the chain saw, they are
subject to a certain degree of wear. They must be
inspected regularly by DOLMAR authorized service
centers. This measure is for your own safety.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes. (Fig. 44)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
After replacing brushes, plug in the tool and break in
brushes by running tool with no load for about 10 minutes.
(Fig. 45)
Storing tool
Biologically degradable saw chain oil can only be kept for
a limited period. Beyond two years after manufacture,
biological oils begin to acquire an adhesive quality, and
cause damage to the oil pump and components in the
lubricating system.
– Before taking the chain saw out of service for a longer
period, empty the oil tank and fill it with a small quantity
of engine oil (SAE 30).
– Run the chain saw briefly to flush all residue of the
biological oil out of the tank, lubricating system and
saw mechanism.
NOTE:
• When the chain saw is taken out of service, small
quantities of chain oil leaks from it for some time
afterwards. This is normal, and is not a sign of a fault.
Store the chain saw on a suitable surface.
Before returning the chain saw to service, fill up with fresh
BIOTOP saw chain oil.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by DOLMAR Authorized Service Centers,
always using DOLMAR replacement parts.
TROUBLE SHOOTING
Before asking for repairs, conduct your own inspection
first. If you find a problem that is not explained in the
manual, do not attempt to dismantle the tool. Instead, ask
Dolmar Authorized Service Centers.
