Before each use, inspect the grinder, switch and cord for damage. Check for
damaged, missing, or worn parts. Check for loose screws, misalignment or
binding of moving parts, or any other conditions that may affect the operation.
If abnormal vibration or noise occurs, turn the tool off immediately and have the
problem corrected before further use.
Before cleaning or performing any maintenance, the tool should be unplugged
from the power supply. Using compressed air may be the most effective
cleaning method. Always wear safety goggles when cleaning tools with
compressed air.
WARNING: Do not let brake fluids, gasoline, petroleum-based products, pene-
trating oil, etc., come in contact with plastic parts. They contain chemicals that
can damage, weaken or destroy plastic.
WARNING:When servicing use only identical replacement parts. Use of any
other parts may create a hazard or cause product damage.
WARNING:Use only accessories that are recommended by the manufacturer
for the model. Accessories that may be suitable for one tool may become hazard-
ous when used on another tool.
WARNING:Maintain tools with care. Keep cutting tools sharp and clean. Prop-
erly maintained tools with sharp cutting edges are less likely to bind and are
easier to control.
WARNING:Check extension cords before each use. If damaged, replace im
-
mediately. Never use tool with a damaged cord.
WARNING:To ensure safety and reliability, all repairs should be performed by
a qualified service technician.
