SAWING WOOD
Remember that because the blade cuts on the up-
stroke (pull) instead of the down-stroke (push) as in
the case of the hand saw, the good or finish side
of the work should face down (away from the
machine) during cutting.
PLUNGE CUTS
Caution: Do not plunge cut metal materials.
This machine can be used for plunge cutting wood,
plywood, drywall and plastic materials.
Clearly mark line of cut on the work.
Hold the front housing with one hand and the
rear handle with the other.
To start the cut, rest the saw on the cutting shoe,
align the blade with the intended line of cut with
the blade NOT touching the workpiece. Start the
saw. Using the shoe as a pivot point, carefully pivot
the saw forward by raising rear handle until
contact with the workpiece is made. Cut slowly
until the blade has cut through the work and
continue raising the rear handle until the saw is
fully perpendicular to the workpiece. Then
continue the cut normally.
POCKET CUTS IN METAL
Since it isn’t possible to blind cut in metal, The
blade entry point must be started by a different
method. Create a slot using an angle grinder or by
drilling a starter hole with a drill.
SAWING METAL
When cutting angle metals such as channel
section, I-beam, etc., start the cut in a position
where the greatest number of teeth will contact
the work.
To extend blade life, cutting oil can be applied to
the work surface along the line of the cut.
MAINTENANCE
KEEP TOOL CLEAN
Periodically blow out all air passages with dry
compressed air. All plastic parts should be cleaned
with a soft damp cloth. NEVER use solvents to
clean plastic parts. They could possibly eat into or
dissolve the material.
Wear safety glasses while using compressed air.
* BRUSH INSPECTION
* REPLACEMENT PARTS
When servicing use only identical replacement
parts.
SERVICE AND REPAIRS
All tools will eventually require servicing or
replacement of parts due to wear from normal use.
Always use a qualified service center. SERVICE
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
Caution: Always replace the brushes as a pair
To replace:
simply remove the brush caps and withdraw the
old brushes. Replace with new brushes (always
replace as a pair) ensuring that they align properly
and slide freely. Then replace the brush caps.
