Stroke Length and Material
Thickness:
The length of stroke for the H0799
Reciprocating Saw is 1
3
⁄
16
". When mate-
rial thickness exceeds 1
3
⁄
16
" the blade is
unable to evacuate the chips being pro-
duced. Therefore, when cutting materials
that are thicker than 1
3
⁄
16
" it may be nec-
essary 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.

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 are required. A list of TPI and materi-
als 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 thumb
wheel on top of the saw, above the trigger
(see
Figure 3
). The higher the number
on the thumbwheel, the faster the saw
reciprocates.
Using the right blade and speed will allow
faster cutting operation, longer blade life
and will prolong the life of the saw. This
will require practice on the part of the
operator. If blade seems to dull quickly,
replace and use slower blade speed. If
cutting wood, most species allow faster
speeds.
NOTE: When cutting metal, a suitable
coolant must be used (cutting oil); other-
wise it will cause unnecessary wear on
the blade.
Never extract or insert the blade into
workpiece with the blade in motion.
Serious personal injury will occur.
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).
