WARNING:
NEVER adjust the automatic oiler system when the engine
is running. Doing so or failure to heed this warning could
cause serious personal injury.
ADDING BAR AND CHAIN LUBRICANT
See Figure 6.
NOTICE:
Remove battery pack from unit. Fill oil tank with bar and
chain lubricant (not provided) before starting the chain
saw. Failure to lubricate the chain will cause damage to
the bar and chain.
Use bar and chain lubricant (not provided) that is formu-
lated to perform over a wide temperature range with no
dilution required.
NOTE: Do not use dirty, used or otherwise contaminated
lubricants. Damage may occur to the bar or chain.
Carefully pour the bar and chain lubricant into the tank.
Check and fill the oil tank when battery is recharged, or
as needed.
NOTE: It is normal for lubricant to seep from the saw when
not in use. To prevent seepage, empty the oil tank after each
use. When storing the unit for a long period of time (three
months or longer) be sure the chain is lightly lubricated; this
will prevent rust on the chain and bar sprocket.
NOTICE:
Before each use, check to make sure that the chain is
properly tensioned. A cold chain is correctly tensioned
when there is no slack on the underside of the guide bar,
the chain is snug, and it can be turned by hand without
binding. During normal saw operation, the temperature
of the chain increases. The drive links of a correctly ten-
sioned warm chain will hang approximately .050 in. out
of the bar groove.
See the Adjusting the Chain Tension instructions in the
Maintenance section of this manual to properly adjust
the chain tension.
OPERATING THE CHAIN BRAKE
See Figures 7 - 8.
Check the operating condition of the chain brake prior to
each use.
Using the back of your left hand, engage the chain brake
by pushing the chain brake lever/front hand guard toward
the bar while the chain is rotating rapidly.
OPERATION
Reset the chain brake back into the RUN position by
grasping the top of the chain brake lever/front hand guard
and pulling toward the front handle until you hear a click.
WARNING:
If the chain brake does not stop the chain immediately, or
if the chain brake/front hand guard will not stay in the run
position without assistance, take the saw to an authorized
service center for repair prior to use.
STARTING AND STOPPING THE CHAIN SAW
See Figures 9 - 10.
WARNING:
Keep body to the left of the chain line. Never straddle the
saw or chain, or lean over past the chain line. Improper
operation of the chain saw could result in serious per-
sonal injury.
Starting the chain saw:
Slide and hold the lock-out button. This makes the switch
trigger operational.
Press and hold the switch trigger, release the lock-out
button and continue to squeeze the switch trigger for
continued operation.
Stopping the chain saw:
Release the switch trigger to stop the chain saw.
Upon release of the switch trigger, the lock-out button
will be automatically reset to the lock position.
This cordless chain saw is designed for limbing and pruning
type cutting, as well as cutting small trees.
PREPARATION FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 11 - 12.
Refer to General Power Tool Safety Rules earlier in this manual
for appropriate safety equipment.
Wear non-slip gloves for maximum grip and protection.
Hold the saw firmly with both hands. Always keep your
left hand on the front handle and your right hand on the
rear handle so that your body is to the left of the chain line.
WARNING:
Never use a left-handed (cross-handed) grip, or any
stance which would place your body or arm across the
chain line. Improper operation of the chain saw could
result in serious personal injury.
