User Manual

4. In sawing limbs which have a tendency to split or

tear when making a single saw flush cut, Figure 4, it

is advisable to make more than one cut. The first cut

is made a few inches from the point of the flush cut

removing the weight of the limb being trimmed out

and leaving a short stub. The stub is then flushed off

as shown in Figure 5. Whenever practical, the cut

shall be treated with tree paint if it is larger than 1

inch in diameter. This technique will avoid breaking

the lateral which you are trying to save or splitting

the remaining limb down the center as the flush cut

is made.

FINAL CUT

THE FIRST CUT IS TO TAKE WEIGHT

OFF BEFORE THE FINAL CUT TO

PREVENT THE LIMB FROM SPLITTING

DOWN THE CENTER.

Figure 5. Flush Cut

WARNING

Do not cut material that is directly overhead. When it

falls it may cause operator injury.

Watch the saw reaction to making a cut. Control the

movement of the saw.

6. Release the ON/OFF trigger to stop saw blade rota-

tion.

7. Reposition the saw to make the next cut and con-

tinue operating the saw as stated above.

MAKING CUTS

WARNING

The following are general wood cutting procedures

and techniques. Differences in the terrain,

vegetation, and type of wood will make this

information more or less valid for particular areas.

For advice on specific wood cutting problems or

techniques for your area, consult your local Stanley

representative or your county agent. They can often

provide information that will make your work safer

and more productive.

Move the hydraulic circuit control valve to the

position to pressurize the circuit.

Maintain a firm grip on the saw handle. While main

taining firm footing and balance, position the saw

blade near the material to be cut.

3. Squeeze the ON/OFF valve handle trigger and allow

the saw blade to reach FULL speed.

WARNING

After releasing the ON/OFF trigger, saw operators

must be certain that the saw has come to a complete

must come to a complete stop before placing the saw

into the truck’s bucket, storing the saw or contacting

the blade in any way. Failure to observe this warning

may result in severe personal injury.
