Introduction

Your Roberts 10-475 Professional Floor Stripper machine was
designed for fast efficient removal of VCT, sheetgoods, carpet

quares, and for removal of dried adhesive from all substrates.

s
It features a patented adjustment system, which provides a

range of blade motions from a side-to-side “slicing” motion,

o a back and forth “ chopping” motion. The operator can

t
select the best blade motion pattern for a variety of jobs.

This operator’s manual contains information on machine
operation, safety, care and maintenance. Please read the

anual thoroughly before you begin operating your Stripper.

Electrical Requirements

•

THIS STRIPPER MUST BE CONNECTED TO A GROUNDED
POWER SOURCE while in use to protect the operator from

electrical shock.

• IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,

grounding provides a path of least resistance for electrical
current to reduce the risk of electrical shock. The stripper is
equipped with an electrical cord with a grounding conductor
and a grounding plug. Insert the 3-prong electrical plug into a
3-pole receptacle that is properly installed and grounded in
accordance with all local codes and ordinances.

• DO NOT MODIFY THE PLUG provided if it will not fit the outlet.

Have the proper outlet installed by a qualified electrician.

• IMPROPER CONNECTION OF THE EQUIPMENT-GROUNDING

CONDUCTOR CAN RESULT IN A RISK OF ELECTRIC SHOCK.

The conductor with insulation that is green on the outside
(with or without yellow stripes) is the equipment-grounding
conductor. If repair or replacement of the electrical cord or
plug is necessary, do not connect the equipment-grounding
conductor to a live terminal.

•

CHECK WITH A QUALIFIED ELECTRICIAN or service personnel
if the grounding instructions are not completely understood,
or if in doubt as to whether the tool is properly grounded.

• USE ONLY 3-WIRE EXTENSION CORDS that have 3-prong

grounding plugs and 3-pole receptacles that accept the
stripper’s plug.

• REPAIR OR REPLACE DAMAGED OR WORN CORDS

IMMEDIATELY.

• IF THE PLUG OR RECEPTACLE DOES GET WET, DO NOT

UNPLUG THE CORD. Disconnect the fuse or circuit breaker

that supplies power to the tool. Then, unplug and examine for
presence of water in the receptacle.

•

ONLY UL-LISTED EXTENSION CORDS SHOULD BE USED
WITH THIS PRODUCT.

• DO NOT LET YOUR FINGERS TOUCH THE TERMINALS of plug

when installing or r

•

IMPROPER USE OF EXTENSION CORDS MAY CAUSE
INEFFICIENT OPERATION OF YOUR TOOL, which can result in

overheating. Be sure your extension cord is rated to allow
sufficient current flow to the motor. For the proper gauge for
this stripper, please refer to TABLE 1.

•

THIS MACHINE MUST BE PROPERLY GROUNDED.

The risk of electric shock and bodily injury are greatly
increased if it is not, particularly when used in damp locations
or in proximity to plumbing.

Extension Cords

1. Use only extension cords that are intended for outdoor use.
These extension cords are identified by a marking
“Acceptable for use with outdoor appliances: store indoors
while not in use.” Use only extension cords having an
electrical rating not less than the rating of the product. Do
not use damaged extension cords. Examine extension cord
before using and replace if damaged. Do not abuse
extension cords and do not yank on any cord to disconnect.

eep cord away from heat and sharp edges. Always

K
disconnect the extension cord from the receptacle before
disconnecting the product from the extension cord.

2.

WARNING - To reduce the risk of electrocution, keep all

onnections dry and off the gound. Do not touch plug with

c

et hands.

w

3. Gound Fault circuit Interrupter (GFCI) protection should be

rovided on the circuit(s) or outlet(s) to be used for the

p
stripper. Receptacles are available having built-in GFCI
protection and may be used for this measure of safety.

4.

Use proper extension cord. Make sure your extension cord
is in good condition. When using an extension cord, be
sure to use a cord heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in
line voltage, resulting in loss power and overheating.
TABLE 1 below shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use
the next heavier gauge.
The smaller the gauge number, the heavier the cord.

NOTE: This tool is intended for use on a circuit that has an

outlet that looks like the one illustrated in Fig. 1 (B). The
tool has a grounding plug that looks like the plug illustrated
in Fig. 1 (A). The green-colored rigid prongs extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box.

be adjusted up or down to suit the operator’s preference.

3. Lay the upper (silver) handle assembly (c) down, so the leg with
the holes drilled through is to the left, as it appears in the
drawing. Slide the switch box (D) on to the right leg with the
rocker switch facing up, or it can be mounted on the left leg if
you prefer the switch to be in the center.

4. Slide the upper (silver handle assembly (C) into the lower (red)
handle tubes (B).

5. Tighten the switch locking screw (E). Plug the electric cord
from the switch into the motor cord. Set the handle height at
a desired level, and secure it with the pin on the left leg, and
tighten the screw (F) on the right side. Note the pin on the left
side secures the handle at 1-1/2'' increments up and down.
A clip on the right handle leg secures the power cord.

1. As with any major power tool, keep your Roberts Stripper
clean, and do not leave the machine outside in the weather.

2. Inspect the Stripper regularly. If the blade is chipped, cracked, or
dull, replace it. Roberts’s blades are sharpened on two edges, so
the blade can be reversed and used. Check the electrical cord. If
there are cracks or cuts, immediately replace the cord.

3. Occasionally – every couple of months – turn the Stripper upside
