Silverline Air Cut-Off Tool - Manual (Page 9)

GB
Note: Do not apply too much pressure to the machine whilst grinding.
Excessive pressure does not result in more effective removal of material,
but will cause premature wear of the grinding disc and increase wear and
tear on the machine.
WARNING: This is a cutting device only. DO NOT attempt to use it for
sideways grinding, as axial force will cause the cutting disc to shatter.
1. Hold the tool by its Handle (1) and turn it so the open side of the Guard
(2) is facing away from you. Your thumb should wrap around the
Handle (1) and your fingers should sit on the Speed Control Trigger (9)
2. Disengage the Safety Catch (8) and gently squeeze the trigger towards
the handle
3. The Cutting Disc (5) will begin to spin. Squeeze the trigger further to
increase the speed, slightly release to decrease the speed
4. With the disc spinning at the required speed, slowly move the disc
towards the workpiece to be cut and gently engage the material
WARNING: When the disc begins to cut, it will force the tool to move
sideways. Make sure you have a firm grip on the tool and are ready to
counteract this.
5. As the disc begins to cut, take note of the direction of the waste
material being ejected. It should be going away from you, and not
towards any person or object to which it may cause damage
6. To stop the tool, remove the disc from the workpiece, fully release the
trigger and allow the safety catch to re-engage
Note: DO NOT allow the tool to run in ‘idle rotation’ for an extended period of
time. This will shorten its life.
WARNING: Be aware that air tools may hold residual pressure after use.
Always bleed air pressure from the tool after shutting off air supply.
Accessories

from your Silverline dealer or www.toolsparesonline.com
Maintenance
WARNING: Always disconnect from the air supply and depressurise before
cleaning or carrying out any maintenance.
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts
to wear quickly, and shorten the machine’s service life. Clean the body of
your machine with a soft brush, or dry cloth
IMPORTANT: There is very little that can go wrong with your air tool and it
should be noted that when an air tool fails to work it is generally because
the internal workings have corroded due to dirty, wet air and failure to
follow the instructions given below.
Daily maintenance procedure: Disconnect from the air supply, pour the
equivalent of a tablespoon of oil into the air intake. Operate the machine at
low speed to thoroughly lubricate all internal workings.
• If the machine is in constant use or used for long periods at a time, a
combined filter/lubricator must be fitted. There must be an air filter fitted
at all times
• Use air tool oil only. DO NOT UNDER ANY CIRCUMSTANCES USE NORMAL
ENGINE OIL
• Failure to comply with the operating and maintenance instructions may
invalidate the guarantee
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
Disposal
• As with other power tools, air tools should not be disposed of with
household waste
• Air tools may contain traces of tool oil and other lubricants and so must
be recycled accordingly
• Contact your local waste disposal authority for information on the correct
way to dispose of power tools Troubleshooting
Problem Possible Cause Solution
Tool operating slowly
Pressure incorrect Set the correct air pressure according to the specification
Dirt within the mechanism Pour oil into air inlet as per maintenance instructions
Air blockage Operate tool in short bursts to clear blockage
Air leak Check all fittings and hose for air leaks and correct issue by re-
tightening, using PTFE tape or replacing
Blockage in gauze mesh filter Remove Quick Connector (10) and clean mesh filter
Tool seized
Dirt or rust in mechanism Try ‘Tool operating slowly’ solutions
Dirt or rust in mechanism Tap tool gently with a soft mallet
Dirt or rust in mechanism Free mechanism by rotating drive manually when disconnected from
air line
Strong vibrations when tool is
switched on
