to touch anything while the chain is in motion.

Pressure on Bottom
4. Pole chain saws must be hung securely in a vertical
position to prevent dislodgement. Pole chain saws
must not be hung on utility wires or cables and must
not be left in the tree overnight. Pole chain saws
must be hung so the sharp edge is away from the
worker, if possible.
5. Warnings, when necessary, must be given by the
worker in the tree before a limb is dropped. "Timber"
or "heads up" are common terms used for this
purpose.
6. A separate line should be attached to limbs that
cannot be dropped safely or are too heavy to be
controlled by hand. The line should be held by
workers on the ground end of the rope. Use of the
same crotch for both the safety rope and the work
rope should be avoided.
7. The safety line or climbing rope must not be used for
any purpose but for climbing.
8. Cut branches must not be left in trees overnight.
TOPPING/LOWERING LIMBS
1. Observe all safety precautions.
2. Use both hands. Keep a firm grip.
3. Workers performing topping operations should
make sure the trees are able to stand the strain of
a topping procedure. If not, some other means of
lowering the branches should be provided, such as
a tree crane.
4. If large limbs are lowered in sections, the worker in
the tree should be above the limb being lowered.
5. Guidelines, hand lines, or tag lines must be used
OPERATION
when conditions warrant their use.
LIMBING AND BUCKING
1. Observe all safety precautions.
2. Use both hands. Keep a firm grip.
3. When it is possible to do so, the tree worker must
work on the side opposite the side on which the limb
is being cut.
4. Branches bent under tension must be considered
hazardous.
COLD WEATHER OPERATION
If the pole chain saw is to be used during cold weather,
preheat the hydraulic fluid at low engine speed. When
using the normally recommended fluids, fluid should be
at or above 50 °F/10 °C (400 ssu/82 centistokes) before
use.
Damage to the hydraulic system or pole chain saw can
result from use with fluid that is too viscous or thick.
Cutting frozen wood causes the cutters to wear,
crack and break at the back rivet hole unless proper
precautions are taken. To extend chain life when cutting
in cold weather:
• Be sure the automatic oiler is working.
• Keep the chain tensioned and check often.
• Keep the chain properly sharpened. Touch up at
least every hour. Never force a dull chain to cut.
• Clean out the bar groove and keep the oil hole open.
Turn the bar over to equalize wear on the rails.
• Always install a new sprocket with a new chain.
AUTOMATIC OILER ADJUSTMENT
1. Observe all safety precautions.
2. The automatic oiler is located in the front of the
motor housing. The oil volume can be adjusted with
a 3/16 inch Allen wrench by turning the plug counter-
clockwise to increase output and turning clock wise
to decrease output.
Note: Oil output varies proportionally to load and
operating pressure. It should be adequate for most
operations as adjusted from the factory.
3. Initial oiler adjustment is made with the saw bar and
chain removed.
The following step can be hazard ous. Failure to
heed the instructions could result in serious injury.
4. Connect the pole chain saw to a hydraulic power
source and check for proper operation. READ
