Instructions

Procedures not specifically explained in this manual must be performed only by a qualified technician.

To prevent serious injury

from accidental operation:

Turn off the tool, detach the air supply, safely discharge any residual air pressure in the tool, and release the Trigger before performing any inspection, maintenance, or cleaning procedures.

To prevent serious injury from tool failure:

Do not use damaged equipment. If abnormal noise, vibration,

or leaking air occurs, have the problem corrected before further use.

To prevent explosion: Lubricate the tool only with specified lubricants. Lubricate the air inlet using only pneumatic tool oil. Lubricate the internal mechanism using only white lithium grease. Other lubricants may damage the mechanism and may be highly flammable, causing an explosion.

Cleaning, Maintenance, and

Lubrication

Daily - Air Supply Maintenance: Every day, perform maintenance on the air supply according to the component manufacturers’ instructions. The lubricator’s oil level needs to be maintained and the moisture filter must be regularly drained. Performing routine maintenance on the air supply will allow the tool to operate more safely and will also reduce wear on the tool.

After each use, wipe off the tool, clean out any accumulated saw dust, and replace the sandpaper as needed.

If the Trigger (26) begins to stick, apply a few drops of oil and pump the Trigger to distribute the oil.

Note: These procedures are in addition to the regular checks and maintenance explained as part of the regular operation of the air-operated tool.
