Felling Tree with Chain Saw (SEE). (Cont)

TM 5-2420-224-10

WARNING

Use extreme caution when cutting small brush and saplings with chain saw. Slender

material may catch chain, whipping chain toward operator or pulling operator off

balance resulting in personal injury.

When cutting limb under tension, be alert for spring-back of limb. Failure to do so

could result in personal injury.

Keep hand grips dry, clean, and free of oil. Failure to do so could result in personal

injury.

Guard against kickback. Kickback is upward motion of bar that occurs when chain at

nose of bar contacts object. Kickback can lead to dangerous loss of control of chain

saw resulting in personal injury. Observe following procedures to avoid kickback:

Hold chain saw firmly with both hands.

Do not allow nose of bar to contact log, branch, ground, or any other obstruction.

Do not overreach.

Do not cut above shoulder height.

Make sure chain tension is adjusted and automatic oiler is working properly. Failure

to do so could result in personal injury or death. (Refer to page 3-18 for tension

adjustment.)

CAUTION

Hydraulic tools switch must be in off position when coupling or uncoupling hydraulic

tools. Failure to do so will result in damage to quick-disconnect couplers and

overheating of hydraulic system.

If hydraulic hand tools are to be in operation during winter, couple two auxiliary hose

reel ends together to preheat hoses and hydraulic oil and prevent equipment

damage.

Make sure vehicle is not within area of tree to be felled. Failure to do so could result

in equipment damage.

(a) Clear area to obtain good footing.

(b) Clear area where tree will fall.

(d) Remove chain saw from hydraulic accessory box.

(e) Connect chain saw to hydraulic quick-disconnect couplers.

(f) Energize tool circuit.
