OPERATION
(continued)
HANDPIECE ADJUSTMENT
TROUBLESHOOTING
The system will be diffi cult to control if
the air pressure or SPM is incorrect. Use
the lowest air pressure setting to provide
proper operation; do not set the air
pressure higher than needed.
• Handpiece vibrates or knocks
without using the foot control: air
pressure is too low; increase to
proper air pressure.
• Handpiece power decreases at full
throttle: air pressure is too low or
the SPM is too high; reset pressure
or SPM.
• Handpiece does not operate within
3/8" (9.525 mm) of depressing foot
throttle: air pressure is too high;
decrease to proper air pressure.
Make fi ne adjustments in air pressure or
SPM until proper operation is attained.
The handpiece will operate smoothly
and predictably once adjusted properly.
With more experience, experiment with
variations in air pressure and SPM to suit
preferences.
FOOT THROTTLE OPERATION
• Place foot on throttle as shown in
FIG. 6, with heel completely on the
foot throttle and not on the fl oor.
• Before depressing foot throttle,
position handpiece and tool
properly. The tool should rest fi rmly
on the material surface before
operating the foot throttle.
After handpiece is adjusted properly,
depress the foot throttle to activate the
handpiece. To increase power when
cutting deeper, depress the foot control
as needed to increase handpiece power.
It may take practice to coordinate foot
action with the need for more power.
Rely on increasing the power provided by
the foot throttle to the handpiece instead
of manually pushing the handpiece
through the cut. Manual pushing is an
incorrect use of the handpiece and can
result in the tool slipping.
At the start of the cut, smoothly increase
power; as more power is needed,
depress the foot throttle more. As the cut
reaches the end, gradually reduce foot
throttle pressure and quickly guide the
graver up and out.
