LOCKOUT PROCEDURES
PREPARATION
1. Notify all affected workers that a lockout is required
and the reason for the lockout of the machine.
MACHINE OR EQUIPMENT SHUTDOWN AND ISOLATION
1. If the equipment is operating, shut it down by
the normal stopping procedure (turn off the
switch). We recommend to install a padlock to
the Electrical control panel.
2. Disconnect the electrical plug from the
electrical source.
APPLICATION OF LOCKOUT / TAGOUT
1. Lock out and tag the switch with an assigned,
individual lock. A worker will not be protected
unless he/she uses his/her own padlock.
2. If more than one worker is working on the same
piece of equipment at the same time, each one
should lock out the equipment, by placing a
personal lock and tag on the group lockout
device when he/she begins work and should
remove those devices when he/she stops
working on the machine or equipment.
3. Locks and tags should clearly show the name of
the person who applied the device, the date,
and the reason for the lockout. This identifies
who is servicing the machinery or equipment. In
a multiple lockout/tagout situation, it will also
identify any worker(s) who may not have
finished working.
4. Locks and tags must be durable enough to
withstand the environment in which they are to
Operator Manual - GRIND PRO DUAL
Landis International - 5
be used. Information on the locks and tags
should remain legible.
5. Locks must be substantial enough to prevent
removal without the use of excessive force.
Tags must be substantial enough to prevent
accidental or inadvertent removal.
6. Both locks and tags are to be standardized by
color, shape, or size. Tags should be easily
recognized and provide appropriate
information about the lockout.
RELEASE FROM LOCKOUT / TAGOUT
1. Before locks and tags are removed and
electricity is restored to the machine, inspect
the work area to ensure that non-essential
items have been removed and that machine
components are operationally intact.
2. Ensure workers are a safe distance from any
potential hazard.
3. The lock and tag should be removed from
each energy-isolating device by the worker
who applied the lock and tag.
4. Notify affected workers that locks and tags
have been removed.

DUST BAG
Dust composed of leather, rubber and plastic is
combustible and can readily be set on fire by a
lighted cigarette or sparks. This can occur
whether the dust is in the dust bag or the
machine duck work leading to the dust bag. Do
not sand or grind metal with the sander.
The cleaner you keep the dust bag, the less
likely you are to burn a hole in it. Failure to shake
the dust bag daily will not only increase this
likelihood, but will also cause a significant loss of
dust extraction from the sanding areas.
✓ Maintenance is important,
see our recommendations page 12.

MONTHLY MAINTENANCE
1. V-Belt – Check tension and adjust if necessary.
V-BELT ADJUSTMENT AND REMOVAL
The V-Belt on the Landis Sander should be checked monthly for proper
tension and general condition. Loose V-Belt will decrease the power
available to the various tools and lower the efficiency of your Sander.
If you discover a worn or frayed belt, replace it now so it won’t break at an
inconvenient time.
• DISCONNECT ELECTRICAL POWER SUPPLY BEFORE WORKING ON THE MACHINE.
TO CHECK V-BELT TENSION
1. Disconnect the electrical power
supply.
2. Remove the 2 bolts of the white
guard box beside the motor. You
will access to the V-Belt.
