OPERATION , CONT’D
Stroke Length and Material
Thickness:
The length of stroke for the G8599
Cordless Reciprocating Saw is 7 ⁄
8
". When
material thickness exceeds 7 ⁄
8
" the blade is
unable to evacuate the chips being pro-
duced. Therefore, when cutting materials
that are thicker than 7 ⁄
8
" it may be neces-
sary to "clear the blade" occasionally.
Simply let go of the trigger and allow the
blade to come to a complete stop. Extract
the blade from the cut and the chips
should fall away. Insert the blade into the
cut and continue cutting.
Operating this equipment has the potential to propel debris into the air which can
cause eye injury. Always wear safety glasses or goggles when operating equip-
ment. Be certain the safety glasses you wear meet the appropriate standards of the
American National Standards Institute (ANSI).

Choosing the Right Blade:
The rule of thumb for choosing a blade for
a given application is that the harder
and/or thinner the material the more teeth
per inch is required. A list of TPI and mate-
rials to be cut follows.
TPI Material
24 Sheet Metal / Stainless
14 Metal / Wood w/ Nails
10⁄14 Soft Metals / Wood
10 Wood
6 Rough Cut Wood
Choosing the Blade Speed:
Blade speed is controlled by the trigger.
The more the trigger is depressed the
faster the blade reciprocates. This allows
speed control from 0-2800 RPM.
Using the right blade and blade speed will
allow faster cutting operation, longer blade
life and will prolong the life of the saw. The
rule of thumb is the harder and/or thicker
the material the slower the speed should
be. This will require practice on the part of
the operator. If blade seems to dull quickly
replace and use slower blade speed. If cut-
ting wood, most species allow faster
speeds.
Never extract or insert the blade into
workpiece with the blade in motion.
Serious personal injury will occur.
