WARNING
IF ANY PARTS ARE MISSING DO NOT OPERATE YOUR TOOL UNTIL THE MISSING PARTS ARE REPLACED FAILURE TO DO SO COULD RESULT FROM POSSIBLE SERIOUS PERSONAL INJURY

Make sure the power supply is 110.120 volts, 60 HZ, AC only.
Before attempting to use your Sander, familiarize yourself with all operating features (See Figure 1) and safety requirements.

WARNING
DO NOT ALLOW FAMILIARITY WITH YOUR SANDER TO MAKE YOU CARELESS. REMEMBER THAT A CARELESS FRACTION OF A SECOND IS SUFFICIENT TO INFLICT SEVERE IN. JURY.

SWITCH
The switch of your sander is equipped with a “lock on” feature which is convenient when standing for extended periods of time. To lock on, simply depress the trigger of the switch, push in the lock button located on the side of the handle, and then while holding the lock button pushed in, release the trigger See Figure 2 To release the lock, depress the trigger and release it. If you have the “Lock-On” feature engaged during use and your Sander becomes disconnected from the power supply, disengage the “Lock-On” feature immediately.

WARNING
BEFORE CONNECTING YOUR SANDER TO THE POWER SUPPLY SOURCE, ALWAYS CHECK TO BE SURE IT IS NOT IN LOCK-ON POSITION, FAILURE TO DO SO COULD RESULT IN THE ACCIDENTAL STARTING OF YOUR SANDER RESULTING IN POSSIBLE SERIOUS INJURY ALSO, DO NOT LOCK THE TRIGGER ON JOBS WHERE YOUR SANDER MAY NEED TO BESTOP PED SUDDENLY.

PREPARING FOR OPERATION
For ease of operation and maintaining proper control, your Sander has a front handle and a rear hand These handles allow two-hand operation which aids in maintaining control, keeping the sanding area level with the workpiece, and keeping hands clear of the sanding bell. When operating your Sander always hold the front handle with your left hand and the rear handle with your right hand as shown in Fig. 2.

WARNING:
KEEP HANDS AND FINGERS CLEAR OF MOVING SANDING BELT, FRONT IDLER PULLEY, AND DRIVE ROLLER ASSEMBLY FAILURE TO DO SO WILL RESULT IN THE SANDING OF YOUR HANDS OR FINGERS. See Fig 3

WARNING
DO NOT LET YOUR FINGERS REST OVER THE FRONT OR RIGHT EDGE OF THE SANDER. IF THE SANDING BELT WERE TO RUN OFF. IF IT WERE NOT PROPERLY ADJUSTED YOUR FINGERS COULD COME IN CONTACT WITH THE MOVING SANDING BELT RESULTING IN POSSIBLE SERIOUS INJURY.

Always operate your Sander as shown in Fig 2.

Selecting the correct size and type of sanding belt is an important step in achieving a high-quality sanded finish. Standard 3-inch x 21-inch sanding belts made of aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding. general, coarse grit will remove the most material and fine grit will produce the smoothest finish in all sanding operations. The condition of the surface to be sanded will determine which grit belt will do the job. If the surface is rough, start with a coarse grit belt sanding until the surface is uniform Medium grit belt may then be used to remove scratches left by the coarser belt, and a fine grit belt used for finishing the surface. Always continue sanding with each grit belt until the surface is uniform.

WARNING:
ALWAYS WEAR SAFETY GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHEN OPERATING YOUR SANDER IFTHE SAN DING OPERATION IS DUSTY, WEAR A FACE OR DUST MASK. FAILURE TO DO SO COULD RESULT IN DUST OR LOOSE PARTICLES: BEING THROWN INTO YOUR EYES, RESULTING IN POSSIBLE SERIOUS INJURY.

INSTALLING AND ADJUSTING THE SANDING BELT DISCONNECTS THE SANDER FROM THE POWER SUPPLY WHILE ASSEMBLING PARTS OR MAKING ADJUSTMENTS.
To release the sanding belt, lift the tension release lever straight up as shown in Figure 4. When sufficient force is exerted, the spring will be compressed allowing the pulley to lock in a rear position. This trees the sanding belt so it can be removed. Install a new belt making sure the arrow inside of the belt is pointing in the direction of rotation, which is clockwise when looking into the open side of the sander. See Fig 5. Roughly align the belt to its correct position, then release ten- sion on the pulley. Release tension by lowering the tension release lever as shown in Figure 6. The pulley will snap back into the operating position.

WARNING:
KEEP HANDS AND FINGERS CLEAR OF THE FRONT IDLER PULLEY AND SPRING MECHANISM AT ALL TIMES FAILURE TO DO SO COULD RESULT IN THEM GETTING PINCHED; RESULTING IN POSSIBLE SERIOUS INJURY.

ALWAYS WEAR SAFETY GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHEN OPERATING YOUR SANDER. To adust sanding bell, connect Sander to power supply. Place Sander in upside down position as shown in Figure 7.

NOTE:
This position is for adjustments only. The Sander Is not in an operating position. Pull switch trigger and release immediately. Observe tracking of sanding belt If the sanding belt runs inward, turn the tracking screw clockwise. If the sanding belt runs outward, turn the tracking screw counterclockwise. This should be done until you are sure belt will not run off sander, or come in contact with internal parts After installing a new sanding belt, it may become necessary to change the adjustment several times until the belt becomes pliable.

WARNING:
IF SANDING BELT BEGINS TO WEAR EXCESSIVELY ON THE INNER EDGE, RE ADJUST TRACKING SCREW. IT IS ADIUSTED TOO FAR INWARD AND THE SANDING BELT IS RUBBING AGAINST INTERNAL PARTS.

When you are sure the belt will not rub against internal parts, start your Sander and fine adjust the tracking screw until the belt stabilizes. See Figure 8. When correctly adjusted, the outer edge of the belt will be even with the outer edge of the base of your Sander. Belt life will be greaily increased if a few seconds are spent adjusting the belt tracking.
