Do not support board or
panel away from the cut.

Do not use dull or damaged blade. Unsharpened
or improperly set blades produce narrow kerf
causing excessive friction, blade binding and
KICKBACK. Keep blade sharp and clean. Gum
and wood pitch hardened on blades slows saw and
increases potential for kickback. Keep blade clean
by first removing it from tool, then cleaning it with
gum and pitch remover, hot water or kerosene.
Never use gasoline.
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.
Use extra caution when making a "Pocket Cut"
into existing walls or other blind areas. The
protruding blade may cut objects that can cause
KICKBACK. For pocket cuts, retract lower guard
using Retracting Lever.
ALWAYS hold the tool firmly with both hands.
NEVER place your hand or fingers behind the
saw. If kickback occurs, the saw could easily jump
backwards over your hand, leading to serious
personal injury.

Never force the saw. Forcing the saw can cause
uneven cuts, loss of accuracy, and possible
kickback. Push the saw forward at a speed so that
the blade cuts without slowing.
12. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Adjust speed of cut to maintain smooth
advancement of tool without decrease in blade
speed.
13. Adjustments. Before cutting be sure depth and
bevel adjustments are tight.
14. Avoid Cutting Nails. Inspect for and remove all
nails from lumber before cutting.
15. When operating the saw, keep the cord away
from the cutting area and position it so that it
will not be caught on the workpiece during the
cutting operation. The tool is provided with a
front grip and rear handle for two hand
operation. Operate with proper hand support,
proper workpiece support, and supply cord
routing away from the work area.
WARNING: It is important to support the
workpiece properly and to hold the saw firmly
to prevent loss of control which could cause
personal injury. Fig. 4 illustrates typical hand
support of the saw.

16. Place the wider portion of the saw base on that
part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made. As examples, Fig. 5
illustrates the RIGHT way to cut off the end of
a board, and Fig. 6 the WRONG way. If the
workpiece is short or small, clamp it down. DO
NOT TRY TO HOLD SHORT PIECES BY HAND!
