Advertenties
Never remove a limb from a tree while it is supporting
your weight.
Be careful of the tip touching other limbs.
Always use both hands.
Don't cut with the saw overhead or the bar in a vertical
position.
If the saw should kickback, you may not have good
enough control to prevent possible injury.
Know how limb is stressed
•
If you have thick branches, work from the outside to
the inside to avoid your bar and chain get stuck.
11.4 BUCK A LOG
Figure 14.
CAUTION
Stay on the uphill side of logs.
Bucking is the sawing of a log or fallen tree into smaller
pieces. There are a few basic rules which apply to all
bucking operations.
•
Keep both hands on the handles at all times.
•
Support logs if possible.
•
When cutting on a slope or hillside, always stand
uphill.
NOTE
No standing on log.
11.5 TENSION AND COMPRESSION IN
TIMBER
Figure 15-17.
CAUTION
If you have misjudged the effects of tension and
compression, and cut from the wrong side, the timber
will pinch the guide bar and chain, trapping it. If the
chain should become jammed and the saw can not
be removed from the cut do not force it out. Stop the
saw, force a wedge into the cut to open it up. Never
force the saw when it is jammed. Do not force the
saw into the cut. A dull chain is unsafe and will cause
excessive wear to the cutting attachments. A good
way to tell when the chain is dull is when fine saw dust
comes out instead of chips.
A length of timber lying on the ground will be subject to
tension and compression, depending at which points the
major support is.
•
When timber is supported at its ends the
compression side is at the top and the tension side
is at the bottom.
English (Original Instructions)
•
To cut between these support points, make the
first cut downwards approximately 1/3rd the timber
diameter.
•
The second cut is made upwards and should meet
the first cut.
Heavy stress
•
When the timber is supported at one end only, make
the first cut upwards approximately 1/3rd the timber
diameter.
•
The second cut is made downwards and should
meet the first cut.
Underbuck
•
Make angled cut when one section may settle
against the other.

MAINTENANCE
Do not let brake fluids, gasoline, petroleum-based
materials touch the plastic parts. Chemicals can
cause damage to the plastic, and make the plastic
unserviceable.
Do not use strong solvents or detergents on the
plastic housing or components. Strong solvents or
detergents can cause damage to the plastic housing
or components.
Remove the battery pack from the machine before
maintenance.
12.1 ADJUST THE CHAIN TENSION
Figure 2-7.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take
up the slack.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand.
A slack chain may jump off and cause serious or even
fatal injury.
Wear protective gloves if you touch the chain, bar or
areas around the chain.
1. Stop the machine.
2. Loosen the sprocket cover nuts with the wrench.
