Silverline Air Sheet Metal Shear - Manual (Page 8)

• Ensure that water is drained from air system daily
• Ensure that all parts of the system (hoses, couplers, etc.) are correctly
rated for the air pressure to be used
Setting tool power
• The tool speed/power can be adjusted by reducing/increasing the air
supply pressure within the range specified in ‘Specifications’
• Whilst working with the tool, speed adjustments can be made via the
Speed Control Trigger (2)
Operation
WARNING: Ensure the material to be cut does not exceed the cutting
capacity of this device.
Note: Always mark the line or shape to be cut on the material.
1. Grip the tool firmly, disengage the safety catch integrated into the
Speed Control Trigger (2) and depress the lever to begin cutting
2. Apply light pressure to move the blades through the material, as
shown in Fig. A
Note: If the device stalls whilst cutting, release pressure on the speed
control trigger to turn off the tool. Pull back from the cutting edge. Depress
the lever to restart the cutting process and slowly engage the cut.
3. Release pressure on the Speed Control Trigger to finish cutting, and
ensure the safety catch re-engages to prevent accidental activation
Note: This device is designed for cutting straight lines and gradual curves,
not 90° corners.
Note: DO NOT allow the shear 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.

Maintenance
WARNING: Always disconnect from the air supply and depressurise before
cleaning or carrying out any maintenance.
Replacing blades
Note: Periodically inspect and replace blades as necessary. All three blades
are available to purchase separately (see ‘Accessories’), however, it is
recommended to always replace them as a set.
1. Remove the Blade Retaining Bolts (4) using a 4mm hex key (not
included)
2. Remove the centre blade first, then the left and right blades and
bushing
3. Replace with new blades. Place the bushing between the new left and
right blades (see Fig. B), and insert into the Blade Assembly (1)
4. Insert the three previously removed blade retaining bolts into the body
of the blade assembly, and tighten all three bolts with the hex key
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. 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
