Operator Safety Instructions
EN

A. Cigarette lighters, pilot lights and any other source of ignition can create an explosion when active during a sanding
session. All sources of ignition should be extinguished or removed entirely if possible from the work area.
B. Work areas that are poorly ventilated can create an explosive environment when certain combustible materials are in the
atmosphere, i.e., solvents, thinners, alcohol, fuels, certain nishes, wood dust and other combustible materials. Floor
sanding equipment can cause ammable material and vapors to burn. Read the manufacturer’s label on all chemicals
used to determine combustibility. Keep the work area well ventilated.
C. Spontaneous combustion or an explosion can occur when working with sanding dust. The sanding dust can self-ignite
and cause injury or damage. Sanding dust should be disposed of properly. Always empty the sanding dust into a metal
container that is located outside of any building(s).
D. Remove the contents of the dust bag when the bag is 1/3 full. Remove the contents of the dust bag each time you nish
using the equipment. Never leave a dust bag unattended with sanding dust in it.
E. Do not empty the contents of the dust bag into a re.
F. Hitting a nail while sanding can cause sparks and create an explosion or re. Always use a hammer and punch to
countersink all nails before sanding oors.

SAFETY INSTRUCTIONS
This oor-nishing machine shall be grounded while in use to protect the operator from electrical shock. The machine
is provided with a three-conductor cord and a three contact grounding attachment plug to t the proper grounding type
receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect this wire to other than
the grounding pin of the attachment plug.
This machine is for use on a nominal 120 volt circuit and has a grounding plug that resembles the plug illustarted as (A) in the
sketch. Make sure that the machine is connected to an outlet having the same conguration as the plug. No adapter should
be used with this machine.

Machine Setup
EN
This sanding machine is designed to be operated with a remote vacuum
dust collection system or with the included dust bag.
Preparing Remote Vacuum Dust Collection Systems
To prepare the machine for remote vacuum dust collection systems that
have a 2” hose end, follow this procedure:
1. Install 2” hose end (gure 1, A) directly over the exhaust tube
(gure 1, B).
2. The exhaust tube can be rotated for optimum convenience.
To prepare the machine for remote vacuum dust collection systems that
have a 1 ½” hose end, follow this procedure:
1. Install the 2” x 1½” hose end adaptor (Part No. 30563A) (gure 1, C)
over the exhaust tube (gure 1, B).
2. Insert 1 ½” hose end (gure 1, D) into the adaptor (gure 1, C).
NOTE: Start the remote vacuum collection system before operation.
Preparing to use the included dust bag
To prepare the machine for use with the included dust bag (Part No.
53544B), follow this procedure:
1. Install the dust bag by pressing the end onto the exhaust tube
until the ring locks into the groove (gure 2). This is best done
by pressing on the back of the bag opening with the palm of your
hand.
2. The exhaust tube can be rotated for optimum convenience.
3. To remove the dust bag from the exhaust tube, pry up the end
of the bag opening to partially release the internal rib from the
groove, then pull.
4. To empty the dust bag, unzip the disposal ap and force contents
out by inverting the bag.
NOTE: For best results, empty frequently. Follow all warnings posted
in this manual and on the dust bag.

Adjustment Procedures
Routine Maintenance
EN
Leveling
To adjust the machine leveling follow this procedure:
1. Locate the leveling screw. See Figure 6.
2. Tighten the screw (compress the leveling spring) to sand heavier on drive
belt side of sanding drum.
3. Loosen the leveling screw (relax the leveling spring) to sand heavier on the side
opposite the drive belts.
Condition - Pad creates ridges on both edges or a “hop” is experienced: Rotate
both adjusting screws equal amounts clockwise. Tighten locknuts and test on a
piece of plywood. Repeat procedure until condition is corrected. We recommend
you not exceed 1/8” rotation for each attempt.
Condition - Pad creates a ridge on the tip of the pad: Rotate both adjusting screws
counter clockwise, tighten locknuts and test. Repeat procedure until condition is
corrected. Use only 1/8 rotation for each attempt.
Condition - Pad creates a ridge on only one side of the pad: Either rotate the
adjusting screw of the side effected clockwise or rotate the adjusting screw opposite
counterclockwise, depending on whether the ridge terminates beyond the tip of the
pad or prior to it. If it is prior to the tip, adjust the side effected, otherwise adjust the
opposite side.
Figure 6
Dust Shoe
To adjust the dust shoe follow this procedure:
1. Disconnect machine from power supply.
2. Loosen the four screws fastening the dust shoe to the chassis.
3. Adjust the dust shoe towards the drum to improve recovery of ne particles.
4. Adjust the dust shoe away from the drum to improve recovery of coarse particles.
5. Align the dust shoe with the drum and tighten screws. See Figure 6b.Figure 6b
Sanding Chamber
Periodically blow out the sanding chamber to prevent large accumulations of debris which could interfere with the performance of the dust
recovery system.
Wheels
Periodically remove the debris from the truck and caster wheels. Debris can cause waves on a sanded surface.
Dust Bag
Remove the dust bag from the machine and shake it thoroughly to remove the sanding dust from the dust bag. Turn the dust bag inside out and
machine wash in cold water to prevent pore blockage and loss of dust recovery.
Drive Belt
Periodically check the drive belts for broken cogs or frayed edges. Frayed edges may indicate poor tracking. Realign effected belt.
Bearings
Periodically check the bearings for wear or damage according to the following schedule.
Arbor shaft: Re-lubricate every 150 hrs. w/.10 oz. of a NLGI grade 2, -300F to 2500F, 58-75 SUS at 2100 F, grease lubricant.
Motor shaft: After 1st 5000 hrs.
Fan shaft : After rst 1500 hrs.
CAUTION: Failure to perform maintenance at recommended intervals may void warranty.
CAUTION: Maintenance and repairs performed by unauthorized personnel could result in damage or injury. Maintenance and repairs performed
by unauthorized personnel will void your warranty. Failure to perform maintenance at recommended intervals may void warranty.
