„ 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.
STARTING AND STOPPING THE CHAIN SAW
See Figure 7.
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 trees up to 10 in. in diameter
only.
PREPARATION FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 8 - 10.
Refer to Chain Saw Safety Warnings earlier in this manual
for appropriate safety equipment.
„ Wear non-slip gloves for maximum grip and protection.
OPERATION
„ 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.
„ Maintain a proper grip on the saw whenever the unit is
running. The fingers should encircle the handle and the
thumb is wrapped under the handlebar. This grip is least
likely to be broken (by a kickback or other sudden reaction
of the saw). Any grip in which the thumb and fingers are
on the same side of the handle, is dangerous because a
slight kick of the saw can cause loss of control.
WARNING:
Do not operate the switch trigger with your left hand and
hold the front handle with your right hand. Never allow any
part of your body to be in the chain line while operating
a saw. Improper operation of the chain saw could result
in serious personal injury.
PROPER CUTTING STANCE
See Figure 11 - 12.
WARNING:
Always use the proper cutting stance described in this
section. Never kneel when using the chain saw, except
when felling a tree as illustrated in figure 12. Kneeling
could result in loss of stability and control of the chain
saw, resulting in serious personal injury.
„ Weight should be balanced with both feet on solid ground.
„ Keep left arm with elbow locked in a "straight arm" posi-
tion to withstand any kickback force.
„ Your body should always be to the left of the chain line.
„ Thumb should be on underside of handlebar.
BASIC CUTTING PROCEDURE
Practice cutting a few small logs using the following tech-
nique to get the "feel" of using the saw before you begin a
major sawing operation.
„ Take the proper stance in front of the wood with the saw
off.
„ Squeeze the switch trigger and let the chain accelerate
to full speed before entering the cut.
„ Begin cutting with the saw against the log.
„ Keep the unit running the entire time you are cutting,
maintain a steady speed.
