increasethe danger ofkickback.Keep extra bladeson
hand, so that sharpblades are alwaysavailable.
Gum and woodpitchhardenedon bladeswillslow

water, or keroseneto remove these accumulations. Do
not use gasoline.
BLADE GUARD SYSTEM
The lower blade guard attached to your trim saw is
there for your protection and safety. R should
never be altered for any reason. If it becomes
damaged or begins to return slow or sluggish, do
not operate your saw until the damage has been
repaired or replaced. Always leave guard in
operating position when using saw.
& DANGER: When sawingthroughworkpiece,
lower blade guarddoes notcover bladeon the
underside ofworkpiece. Since blade is exposed
on undersideofworkpiece, keep handsand
fingers away from cuttingarea. Any part ofyour
bodycoming in contact withmoving blade will
resultin serious injury.SeeFigure 6.

DANGER: Release switch"immediately ifblade

KICKBACK IS CAUSED BY;

• Forcinga cut.
• Cuttingwarpedor wet lumber.
• Tool misuseor incorrectoperating procedures.
TO LESSEN THE CHANCE OF KICKBACK:
• Always keep the correct blade depth setting- the
correctblade depth settingfor all cuts shouldnot
exceed 1/4 in. below the matedal to be cut. See
Figure 9. One blade toothbelow the material to be
cutworks bestfor most efficientcuttingaction.

• Inspectthe workpiece for knotsor nailsbefore
beginninga cut. Never saw intoa knot or nail.
• Make straightcuts. Always use a straight edge
guide when ripcutting.This helpsprevent twisting
the blade in the cut.
Always use clean, sharp and propedy set blades.
Never make cutswith dull blades.
To avoid pinchingthe blade, supportthe workpiece
propedy before beginninga cut. The right and
wrong ways to support large pieces of workare
shown infigures 8 and 10.

n When making a cut use steady, even pressure.
Never force cuts.
i Do not cutwarped or wet lumber.
[] Always holdyour saw firmlywith bothhands and
keep your bodyin a balanced positionso as to
resist the forces of kickbackshoulditoccur.
_When using your saw, always stay alert and
exercise control. Do not remove your saw from
workpiece while the blade is moving.
DEPTH OF CUT ADJUSTMENT
Always keep correctblade depth setting.The correct
blade depthsettingfor all cuts shouldnot exceed 1/4
inch below the materialto be cut. More blade depth
willincrease thechance of kickbackand cause the cut
to be rough. One blade toothbelow the materialto be

RIP GUIDE (EDGE GUIDE)
Use the rip guide providedwith yoursaw when
making wide ripcuts. A five inchscale has been
providedon the rip guide. When usingthe widthof cut
scale on the base in combinationwith the rip guide,
cutscan be made up to 6 in. to the leftofthe blade or
8-3/4 in. to the rightof the blade.
