No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machines there is danger associated
with this machine. Accidents are frequently
caused by lack of familiarity or failure to pay
attention. Use this machine with respect
and caution to lessen the possibility of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.

Working Clearances
Figure 5
Unsupervised children and
visitors inside your shop
could cause serious per-
sonal injury to themselves.
Lock all entrances to the
shop when you are away and
DO NOT allow unsupervised
children or visitors in your
shop at any time!
For opti-
mum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated.
Site ConsiderationsClean Up
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Lack of ventilation
while using these sol-
vents could cause seri-
ous personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.
