OPERATION
Lubrication
(Fig. 17)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before lubricating the saw chain.
Lubricate the saw chain and bar using a biologically
degradable saw chain oil with an adhesion agent. The
adhesion agent in the saw chain oil prevents the oil from
being thrown off the saw excessively quickly. Mineral oils
must not be used, as they are harmful to the environment.
CAUTION:
• Prevent the oil from coming into contact with the skin
and eyes. Contact with the eyes causes irritation. In the
event of eye contact, flush the affected eye
immediately with clear water, then consult a doctor at
once.
• Never use waste oil. Waste oil contains carcinogenic
substances. The contaminants in waste oil cause
accelerated wear of the oil pump, the bar and the
chain. Waste oil is harmful to the environment.
• When filling the chain saw with chain oil for the first
time, or refilling the tank after it has been completely
emptied, add oil up to the bottom edge of the filler neck.
The oil delivery may otherwise be impaired.
Clean the area around the oil filler cap shown in the figure
thoroughly to prevent any dirt from entering the oil tank.
(Fig. 18)
Unscrew the oil filler cap and add oil up to the lower edge
of the filler neck.
Screw the oil filler cap firmly back in place.
Wipe away any spilt chain oil carefully.
When the chain saw is used for the first time, it may take
up to two minutes for the saw chain oil to begin its
lubricating effect upon the saw mechanism. Run the saw
without load until it does so (see "CHECKS").
CHECKS
Before starting work, carry out the following checks:
Checking the chain tension (Fig. 19)
WARNING:
• Always withdraw the mains plug before checking the
chain tension, and wear safety gloves.
The saw chain is correctly tensioned when it is in contact
with the underside of the bar and can be raised
approximately 2 - 4 mm from the bar by light finger
pressure.
Check the chain tension frequently, as new chains are
subject to elongation. A chain which is too slack can jump
off the bar, and therefore presents an accident risk.
If the chain is too slack: Refer to the section titled
"Adjusting saw chain tension" and adjust the saw chain
tension again.
Checking the switch action
CAUTION:
Always unplug the tool before testing the switch trigger.
Locking the switch trigger in the ON position is prohibited.
(Fig. 20)
It must not be possible to depress the switch trigger
unless the lock-off button is first depressed.
The switch trigger must not jam in the depressed position.
When released, the switch trigger must return
automatically to the OFF position, and the lock-off button
must return to its original position.
Checking the chain brake
NOTE:
• If the chain saw fails to start, the chain brake must be
released. Pull the hand guard backwards firmly until
you feel it engage.
Hold the chain saw with both hands when switching it on.
Hold the rear handle with your right hand, the front handle
with your left. The bar and the chain must not be in
contact with any object.
First press the lock-off button, then the switch trigger. The
saw chain starts immediately.
Press the hand guard forwards using the back of your
hand. The saw chain must come to an immediate
standstill. (Fig. 21)
CAUTION:
• Should the saw chain not stop immediately when this
test is performed, the saw may not be used under any
circumstances. Consult a DOLMAR specialist repair
shop.
Checking the run-down brake
Switch on the chain saw.
Release the switch trigger completely. The saw chain
must come to a standstill within one second.
CAUTION:
• Should the saw chain not come to a stop within one
second when this test is performed, the saw must not
be used. Consult a DOLMAR specialist repair shop.
Checking the chain oiler
Before starting work, check the oil level in the tank, and
the oil delivery.
The oil level can be seen in the sight glass shown in the
figure. (Fig. 22)
Check the oil delivery as follows:
Start the chain saw.
With the saw running, hold the saw chain approximately
15 cm above a tree trunk or the ground. If lubrication is
adequate, the oil spray will produce a light oil trace.
Observe the wind direction, and do not expose yourself to
the oil spray unnecessarily.
CAUTION:
• If an oil trace is not formed, do not use the saw. The
lifespan of the chain will otherwise be reduced. Check
the oil level. Clean the oil feed groove and the oil feed
hole in the bar (refer to "MAINTENANCE").
WORKING WITH THE CHAIN SAW
Bucking (Fig. 23)
For bucking cuts, rest the serrated rail shown in the figure
on the wood to be cut.
With the saw chain running, saw into the wood, using the
rear handle to raise the saw and the front one to guide it.
Use the serrated rail as a pivot.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the serrated
rail further down the timber and raise the front handle
again.
