with only one hand can result in loss of control.
Vibration Precautions
This tool vibrates during use. Repeated or long-term
exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration‑related injury:
1. Anyone using vibrating tools regularly or for an
extended period should rst be examined by a
doctor and then have regular medical check-ups to
ensure medical problems are not being caused or
worsened from use. Pregnant women or people
who have impaired blood circulation to the hand,
past hand injuries, nervous system disorders,
diabetes, or Raynaud’s Disease should not use this
tool. If you feel any symptoms related to vibration
(such as tingling, numbness, and white or blue
ngers), seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and ngers,
increasing the risk of vibration‑related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping

Lubrication
An in-line filter-regulator-lubricator (fig 1) is recommended
as it increases tool life and keeps the tool in sustained
operation. The in-line lubricator should be regularly
checked and filled with air tool oil. Proper adjustment of
the in-line lubricator is performed by placing a sheet of
paper next to the tools exhaust ports and holding the
throttle open approximately 30 seconds. The lubricator is
properly set when a light stain of oil collects on the paper.
Excessive amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for
an extended period of time (overnight, weekend, etc.), it
should receive a generous amount of lubrication through
the air inlet (fig 3). The tool should be run for
approximately 30 seconds to ensure oil has been evenly
distributed throughout the tool. The tool should be stored
in a clean and dry environment.
Recommended lubricants: Use air tool oil or any other
high grade turbine oil containing moisture absorbent, rust
inhibitors, metal wetting agents and an EP (extreme
pressure) additive. (See Fig. 3 for location/air inlet).
and detach the air supply, safely discharge
any residual air pressure, and release
the throttle and/or turn the switch to its off
position to prevent accidental operation.
Note: Residual air pressure should not be present
after the tool is disconnected from the air supply.
However, it is a good safety measure to attempt to
discharge the tool in a safe fashion after disconnecting
to ensure that the tool is disconnected and unpowered.
