• Follow instructions for lubricating and changing
accessories.

• Check for damaged parts. Check for alignment of
moving parts, binding, breakage, mounting and any
other condition that may affect tool's operation.

• Poorly maintained tools and machines can further
damage the tool or machine and/or cause injury.

• A guard or any other part that is damaged should be
repaired or replaced. Do not perform makeshift repairs.

TOOL OPERATION

• Avoid accidental start-up. Make sure that the tool is in
the “OFF” position before plugging in.

• Use the right tool for your job. Do not force your tool or
attachment to do a job for which it was not designed.

• Disconnect tool when changing parts.

• Don't force the workpiece on the machine. Damage to
the machine and/or injury may result.

• Never leave tool running unattended. Turn the power off
and do not leave tool until it comes to a complete stop.

• Do not overreach. Loss of balance can make you fall
into a working machine, causing injury.

• Never stand on tool. Injury could occur if the tool tips, or
if you accidentally contact the cutting tool.

• Know your tool. Learn the tool’s operation, application
and specific limitations before using it.

• Use a proper extension cord of the correct gauge. Your

extension cord should have a grounding prong, and
should be in good condition.

• Handle workpiece correctly. Keep hands away from
moving parts.

• Turn tool off if it jams.

• Always feed workpiece against the direction of the

sanding rotation. To maintain control, properly support
long or wide work-pieces.

CAUTION: Think safety! Safety is a combination of
operator common sense and alertness at all times when
tool is being used.

WARNING

Do not attempt to operate tool until it is completely
assembled according to the instructions.

may cause overheating and motor burn-out. Heavy loads
require that voltage at motor terminals be no less than the
voltage specified on nameplate.

• Power supply to the motor is controlled by a locking
rocker switch. Remove the key to prevent unauthorized
use.

GROUNDING INSTRUCTIONS

A temporary 3-prong to 2-prong grounding adapter (see
Figure 5) may be used to connect this plug to a matching
2-conductor receptacle as shown in figure 5. The temporary
adapter should be used only until a properly grounded
outlet can be installed by a qualified electrician.

ASSEMBLY

WARNING

Improper connection of equipment grounding conductor
can result in the risk of electrical shock.

• The machine should be grounded while in use to protect
operator from electrical shock.

• In the event of an electrical short circuit, grounding
reduces the risk of electrical shock by providing an
escape wire for the electric current.

• This machine is equipped with an approved 3-conductor
cord rated at 150V and a 3-prong grounding type plug
(Figure 4) for your protection against shock hazards.

• Grounding plug should be plugged directly into a
properly installed and grounded 3-prong grounding-type
receptacle, as shown (Figure 4)

• The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.

• Check with a qualified electrician or service personnel if
these instructions are not completely understood or if in
doubt as to whether the tool is properly grounded.

• Do not modify plug provided. If it will not fit in outlet,
have proper outlet installed by a qualified electrician.
Use only 3-wire extension cords, that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as show in
Figure 4

In Canada, the use of temporary adapter is not permitted
by the Canadian Electric Code. Where permitted, the rigid
green tab or terminal on the side of the adapter must be
securely connected to a permanent electrical ground such
as a properly grounded water pipe, a properly grounded
outlet box or a properly grounded wire system.

• Many cover plate screws, water pipes and outlet boxes

are not properly grounded. To ensure proper ground,
grounding means must be tested by a qualified
electrician.

EXTENSION CORDS

Use proper extension cords. Make sure the extension
cord is in good condition. Use only 3-wire extension cords
have 3-prong grounding type plugs and 3-pole
receptacles which accept the tool plug. When using an
extension cord, make sure to use one heavy enough to
carry the current of the machine. An undersized cord will
cause a drop in the voltage, resulting in loss of power and
overheating. Use the table to determine the minimum wire
size (A.W.G.) extension cord.
