Introduction

Introduction

Your WALTER power tool is precision built to meet the highest industrial standards
For maximum performance and longest tool life, follow the operating instructions
and service procedures outlined in this manual.

This tool is CSA certified for both Canada and USA.

This tool is double insulated, it must not be grounded. It may be safely
operated from a grounded or ungrounded receptacle. It is supplied
with a 2-conductor power cord and a polarized plug (one blade wider
than the other). The plug will fit only one way into a polarized outlet. If
the plug does not fit, have the outlet replaced by a qualified electrician.
If an extension cord is necessary, only one that is polarized must be
used. Do not change the plug in any way.

In order to maintain the safety features of the double insulation, the motor housing
must not be drilled to affix nameplates or the like. Self-adhesive labels may be used
for this purpose.

Voltage

Before connecting the tool, check that the voltage shown on the rating plate is the
same as that of the power source.

Operating the tool on a voltage other than specified on its rating plate, may result in
personal injury to the user and damage to the unit.

Extension cord

When an extension cord is required, use one that is heavy enough for the power
demands of the tool.

Extension cords of inadequate wire size cause a serious drop in voltage, loss of
power and possible motor damage.

To limit line voltage drop to a safe level, refer to the following table:

Length in meters 8 15 23 30
Length in feet 25 50 75 100
Wire size AWG 12 12 10 10

Note: Extension cords that are used outdoors, must be approved for outdoor use.

Side handle

Side handle (2) may be mounted on either side of the gear housing for greater
convenience in both right and left hand operation. This handle can also be mounted
on top of the gear housing for superior comfort during cut-off operations.

For reasons of safety and better control, the side handle must always be used.

Rear handle

The rear handle can be turned 90° in either direction. This feature allows for much
improved handling during applications such as cutting and grooving.

To change the rear handle position, press button (4) and rotate handle until you feel
it click into place.

Note: The switch must be turned OFF before rotating the handle. Make sure the
handle is properly positioned and securely locked before starting the tool.
