Topping/Lowering Limbs; Liming And Bucking; Cold Weather Operation - Stanley CS25 User Manual

2. Use both hands. Keep a fi rm grip.
3. Be alert for kickback. Do not allow the tip of the bar 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 can-
not 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 fi rm grip.
OPERATION
3. Workers performing topping operations should make
sure the trees are able to stand the strain of a topping pro-
cedure. 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, handlines, or tag lines must be used when
conditions warrant their use.

LIMING AND BUCKING

1. Observe all safety precautions.
2. Use both hands. Keep a fi rm 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 haz-
ardous.
If the pole chain saw is to be used during cold weather,
preheat the hydraulic fl uid at low engine speed. When us-
ing the normally recommended fl uids, fl uid should be at or
above 50º F/10º C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or pole chain saw can
result from use with fl uid 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:
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 in-
15

COLD WEATHER OPERATION

• 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.
