Operating Instructions

Operation (Continued)

This air tool requires lubrication

before the initial use and before and after each additional use.

Air tools require lubrication throughout the life of the tool. Follow the outlined procedures carefully. Campbell Hausfeld air tool oil (ST1270) is recommended because this oil cleans, lubricates and inhibits rust all in one step.

Air motor Lubrication

The air motor must be lubricated daily. An air motor cannot be oiled too often.

Disconnect the

air tool from the air

supply before lubricating.

1.Disconnect the tool from the air supply.

2.Turn the air tool upside down.

3.Simultaneously (at the same time), pull the trigger and pour a teaspoon of Campbell Hausfeld oil in the air inlet.

After an air tool has been lubri-

cated, oil will discharge through the exhaust port during the first few seconds of operation. Thus, the ex-haust port must be covered with a towel before applying air pressure. Failure

to cover the exhaust port can result in serious injury.

4.Release the trigger and connect the air tool to the air supply. Cover the exhaust port with a towel then run the air tool for 7 to 10 seconds. Oil will discharge from the exhaust port when air pressure is applied. Continue to run the sander until no oil is discharged. Wipe all residual oil from the tool before use.

speed adjustment

This sander is equipped with a regulator for speed adjustment (See Replacement Parts List for Specifications).

attaching sanding pad/dual action sanders

Adhesive backed discs are recommended. To apply the sandpaper, align outside edge and press self adhesive paper onto the pad. Change sandpaper as needed.

Disconnect the air tool from the

air supply before attaching the sanding pad. Do not operate the sander if sanding pad is not securely tightened. Always replace a worn or damaged pad. Serious injury could occur.

1.Lock the drive spindle in place before attaching the sanding pad. Rotate the spindle lock until the spindle lock engages with the drive spindle and hand- tighten the sanding pad in a clockwise direction (See Figure 1).

2.Unlock the spindle before applying air pressure.

NOTE: The spindle lock is for attaching and removing the sanding pad only! Do not operate the tool with the spindle locked or the sander will stall when pressure is applied to the pad.

attaching sanding Discs/high speed sanders

3” or 6” resin discs with non-adhesive backs are recommended. The discs should have 7/8” diameter cutout centers for proper attachment. For best support when using discs larger than 3", use all the backup pads of equal size or smaller than the resin disc itself (See Fig. 2). To install the resin disc, follow the outlined procedures.

Disconnect the air tool from the

air supply before attaching the sanding disc. Do not operate the sander if sanding disc is not securely tightened

or serious injury could occur.

1.Assemble the backup pads as shown in Figure 2. Make sure the recessed center of the pads face the sander.

2.Place the resin disc in front of the appropriate size pad and push the adapter lock down through the center of the pad and discs.

3.Hand tighten the adapter lockdown, then insert the holding tool into the hole shown in Figure 2. Insert a large screwdriver into the slotted hole on the adapter lock down and securely tighten.

dual action sanders

Begin sanding with an abrasive grit coarse enough to remove the high spots and any excessive roughness. Follow with a second sandpaper using a grit one to two ranges finer. Continue with successively finer grits until the desired finish is obtained. Do not change from a coarse grit to a very fine grit in one step. In doing so, it is difficult to remove swirl marks that might have been made by the coarse grit abrasive. Always use the finest grit practical for the sanding operation.

high speed sanders

The coarse resin disc is used for removing or smoothing over welds or blending uneven metal surfaces. The most common grit is 36 (Campbell Hausfeld MP3264 discs).

Worn or damaged sanding discs may

break apart causing serious injury. Always replace discs as needed.

Air hose

Refer to IN170102AV Air Hose Hookup Installation sheet for hookup specifications.

NOTE: It is not recommended to install a quick coupler between the sander and the leader (whip) hose.

Use of a whip hose prevents accidental triggering of the tool when pressurized

air is connected to the system.

In addition, the tool’s vibration wears out quick couplers prematurely.
