LUBRICATION
Always use an air line lubricator with this tool. Aer every

through the tool’s inlet connection. Recommended air tool
oil available from Sidchrome SCMTSATO-250.
SAFE OPERATION
• Always wear eye protection when operating or performing maintenance on this tool.
• Always wear hearing protection when operating this tool.
• Keep hands, loose clothing and long hair away from rotating end of tool.
• Anticipate and be alert for sudden changes in motion during start up and operation of any power tool.
• Keep body stance balanced and rm. Do not overreach when operating this tool.
• Air powered tools can vibrate in use. Vibration, repetitive motions or uncomfortable positions may be harmful to
your hands and arms. Stop using any tool if discomfort, tingling feeling or pain occurs. Seek medical advice before
resuming use.
• Use accessories recommended by Sidchrome®.
• is tool is not designed for working in explosive atmospheres.
• is tool is not insulated against electric shock.
• Always turn o the air supply and disconnect the air supply hose before installing, removing or adjusting any
accessory on this tool, or before performing any maintenance on this tool.

GETTING STARTED
• Always operate, inspect and maintain this tool in accordance with all regulations (local, state, federal and country)
that may apply to hand-held / hand-operated pneumatic tools.
• For safety, top performance, and maximum durability of parts, operate this tool at 90 psig (6.2 bar / 620 kPa) maxi-
mum air pressure at the inlet with 3/4’’ (19mm) inside diameter air supply hose.
• Always turn o the air supply and disconnect the air supply hose before installing, removing or adjusting any
accessory on this tool, or before performing any maintenance on this tool.
• Do not use damaged, frayed or deteriorated air hoses and ttings.
• Be sure all hoses and ttings are the correct size and are tightly secured.
• Always use clean, dry air at 90 psig maximum air pressure. Dust, corrosive fumes and/or excessive moisture can
ruin the motor of an air tool.
• Do not lubricate tools with ammable or volatile liquids such as kerosene, diesel or jet fuel.
• Do not remove any labels. Replace any damaged label.
• e use of a hose whip is recommended. A coupler connected directly to the air inlet increases tool bulk and
decreases tool maneuverability.
• For maximum performance, the coupler on the wall should be the next size larger than the coupler used on the
tool. e coupler closest to the tool should not be less than the proper air supply hose size.
