MT2872L 1.0 HP EXTENDED LENGTH LOW PROFILE CUT-OFF
OPERATION
NOTE: Always shut off air supply, drain hose of air pressure and
disconnect tool from air supply when not in use, before changing
accessories or when making repairs.
NOTE: Before using, test cut-off wheel by briefly running the tool
at full throttle under a barrier (such as under a heavy work table)
to stop any possible broken wheel parts.
Always wear impact-resistant eye and face
protection to
(users and bystanders). Even small projectiles can
injure eyes and cause blindness. A cut-off wheel that
breaks can cause very serious injury. Daily measure the
tool speed with a tachometer to make sure the speed
is not greater than the RPM marked on the cut-off
wheel. Never use a cut-off wheel marked with a
speed lower than the tool speed.

When using the cut-off tool, be careful not to exert excessive
force. Too much force could be hazardous if it causes the
tool spindle to bend or break. The burning of the work piece
or excessive speed reduction indicates too much force being
applied. Start the tool off the work, set it down on the work
evenly and move in the direction desired to make the cut. When
finished cutting, lift off the work before stopping the motor.
Always use the required wheel guard to prevent
injury from broken cutting parts. If a guard has
withstood a wheel breakage, discontinue its use and
replace it with a new guard. It may be damaged.
Position the guard between the cut-off wheel and the operator.
Use barriers to protect others from wheel fragments and sparks.
WARNING: Correct cut-off wheel mounting is necessary to
prevent injury from broken wheels. Do not use chipped or
cracked cut-off wheels. Cut-off wheels should be a free fit on the
spindle to prevent stress at the hole. Use only wheel collars that
come with the tool for mounting the cut-off wheel. Flat washers
or other adapters may over stress the wheel. Tighten the wheel
on the spindle to prevent spin off when the tool is turned off.
WARNING: NEVER OPERATE THIS TOOL
WITHOUT REQUIRED DISC COVER/GUARD
IN PLACE.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
