Kickback is the result of tool misuse and/or incorrect

operating procedures or conditions and can be avoided

by taking proper precautions as given below.

Maintain a firm grip with both hands on the

tool and position your arms to resist kickback

forces. Position your body to either side of

the blade, but not in line with the blade.

Kickback could cause the tool to jump backwards,

but kickback forces can be controlled by the

operator, if proper precautions are taken.

10. When blade is binding, or when interrupting a

cut for any reason, release the trigger and

hold the tool motionless in the material until

the blade comes to a complete stop. Never

attempt to remove the tool from the work or

pull the tool backward while the blade is in

motion or kickback may occur. Investigate and

take corrective actions to eliminate the cause of

blade binding.

11.

When restarting a tool in the workpiece,

center the blade in the kerf and check that

blade teeth are not engaged into the material.

If blade is binding, it may walk up or kickback

from the workpiece as the tool is restarted.

12. Support large panels to minimise the risk of

blade pinching and kickback. Large panels

tend to sag under their own weight. Supports

must be placed under the panel on both sides,

near the line of cut and near the edge of the

panel.

13. Do

not

use

Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade

binding and kickback.

14. Blade depth and bevel adjusting locking

levers must be tight and secure before

making cut. If blade adjustment shifts while

cutting, it may cause binding and kickback.

15. Use extra caution when making a "plunge cut"

into existing walls or other blind areas. The

protruding blade may cut objects that can cause

kickback. For plunge cuts, retract lower guard

using retracting handle.

Lower guard function

16. Check lower guard for proper closing before

each use. Do not operate the tool if lower

guard does not move freely and close

instantly. Never clamp or tie the lower guard

into the open position. If tool is accidentally

dropped, lower guard may be bent. Raise the

lower guard with the retracting lever and make

sure it moves freely and does not touch the blade

or any other part, in all angles and depths of cut.

17. Check the operation and condition of the

lower guard spring. If the guard and the

dull

damaged

spring are not operating properly, they must

be serviced before use. Lower guard may

operate sluggishly due to damaged parts, gummy

deposits, or a buildup of debris.

18. Lower guard may be retracted manually only

for special cuts such as "plunge cuts" and

"compound cuts". Raise lower guard by

retracting handle and as soon as blade enters

the material, the lower guard must be released.

For all other sawing, the lower guard should

operate automatically.

19. Always observe that the lower guard is

covering the blade before placing tool down

on bench or floor. An unprotected, coasting

blade will cause the tool to walk backwards,

cutting whatever is in its path. Be aware of the

time it takes for the blade to stop after switch is

released.

20. To check lower guard, open lower guard by

hand, then release and watch guard closure.

Also check to see that retracting handle does

not touch tool housing. Leaving blade exposed

is VERY DANGEROUS and can lead to serious

personal injury.

Additional safety warnings

21. Do not stop the blades by lateral pressure on

the blade.

22. DANGER:

Do not attempt to remove cut material when

blade is moving.

blades.

CAUTION: Blades coast after turn off.

23. Place the wider portion of the tool base on

that part of the workpiece which is solidly

supported, not on the section that will fall off

when the cut is made.

24. Never attempt to make a cut with the tool held

upside down in a vise. This is extremely

dangerous and can lead to serious accidents.

25. Wear safety goggles and hearing protection

during operation.

26. Always use blades recommended in this

manual. Do not use any abrasive wheels.
