Plunge Cutting; Cutting Metal - Grizzly T10874 Owner's Manual

Plunge Cutting

A plunge cut is a sawing operation in which
the cut is started above the workpiece; the
blade engages the workpiece surface by
"plunging" down through it, then advancing
the cut normally. We recommend avoiding
plunge cutting whenever possible due to
an increased risk of kickback or blade
breakage. Drilling a starter hole or using
a more appropriate tool should be used
instead.
Plunge cuts should never be per-
formed on metal or hardwoods.
Starting saw with blade touching
workpiece could cause kickback,
resulting in serious personal injury.
Tip: Depending on work to be performed,
blade can be installed upside down to aid
in plunge cutting.
To perform plunge cut:
1. Place bottom of pivot foot firmly on
workpiece and align tip of blade with
cut line (see Figure 11).
— If blade is installed upside down, use
opposite side of pivot foot.

2. Hold saw firmly and pull trigger, allow-
ing saw to come up to full speed, then
gradually lower blade tip into panel.
Allow blade to completely penetrate
panel before continuing cut.
3. After blade is through panel (see Figure
12) carefully position pivot foot flush
with workpiece, then finish cut.

Cutting Metal

When cutting metal, always begin at a
low SPM and slowly increase speed. This
will increase the accuracy of the cut and
prevent the blade from jumping around on
the surface of the workpiece. Using cut-
ting fluid will prolong blade life and prevent
over-heating.
To cut metal:
1. Install metal cutting blade.
2. Coat workpiece with cutting fluid.
3. Grasp tool firmly, then pull trigger,
allowing saw to come up to desired
speed.
4. Rest pivot
then ease blade into workpiece.
(see Figure 10 on Page 12).
5. Maintain steady cut speed and pivot
foot pressure until cut is complete.
6. Wait for blade to completely stop
before setting tool down.
