Safety Air Tool Warnings

www.machineryhouse.com.au
www.machineryhouse.co.nz
Warning: Some dust, fumes and gases created by power sanding, sawing, grinding,
drilling, welding and other construction activities contain chemicals that may cause cancer and birth
defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead based paint.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically treated timber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area and work with approved safety
equipment, such as dust masks that are specically designed to lter out microscopic particles.
Technical Specications
Safety Specic For Air Metal Shear
1. ATS-255 shear is designed for cutting sheet
material, such as steel, aluminium and plastics.
If you are not familiar with the proper and safe
operation of a pneumatic shear, do not use
until proper training and knowledge have been
obtained.
2. Secure the workpiece with clamps or in a vise.
 Keepbothhandsontooltopreventlossof
control.
3. Keephandsawayfromthereciprocating
blades.
4. Replace blades if they become damaged or
dull.
4. Do not lubricate the tool with combustible
liquids, such as kerosene, diesel or jet fuel.
5. Do not dispose of this tool with normal
household waste. Never dispose of the air tool
 intore.
6. Use only recommended accessories; improper
accessories may be hazardous.
7. Maintaintoolswithcare.Keepairtoolclean
and oiled for best and safest performance

Any missing parts or damage should be reported immediately to your Toolmaster distributor. Do not use
a damaged tool. Read this instruction manual thoroughly for operation, maintenance and safety
Instructions. The diagram below is the ideal setup position. The lubricator is optional and if not used, then
a few drops of Pneumatic Tool Oil need to be added to the airline connection before operation. Add a few
more drops after each hour of continual use.
WARNING: Operating the tool at pressures over the rated capacity may cause severe
damage and/or personal injury. Do not exceed 90 PSI while operating the tool. Do not
use an accessory rated at a lower maximum pressure than the tool.

Setup
The recommended air system is shown in Fig.1.
1. Useproperairhosesize(refertotoolspecications).Thehoseshouldbejustlongenoughto
serve the working area. Excessive hose length will cause pressure drop.
WARNING! Ensure that the air supply is clean and does not exceed 90psi. Too high an air
pressure and/or unclean air will shorten the life of the air tool due to accelerated wear,
and may cause damage and/or personal injury.
2. Drain the compressor air tank daily. Water in the air line will damage the air tool.
3. Cleanthecompressorairinletlterscreenweekly.
4. Line pressure should be increased to compensate for unusually long air hoses (over 8 meters).
 Theminimumhoseboreshouldbe10mmandttingsmusthavethesameinsidedimensions.
5. Keephosesawayfromheat,oilandsharpedges.Checkhosesforwear,andmakecertainthatall
connections are secure.
IMPORTANT: The leader hose is optional, but connecting a quick-change coupling directly to the
tool is not recommended, as vibration may cause the connection to fail. For the best result, add a
leader hose and install any quick-change couplings further down the line.

Operating Instructions
1. Remove protective cap from air inlet (Fig. 1). If an in-line oiler is not being used, add 4 or 5 drops of
air tool oil (not included) into the air inlet.
2. Blow out air line to remove any dirt or moisture, then connect air supply hose to tool. Set air
pressure to 90 psi.
3. Place cutting blades against workpiece, and both hands on tool.
4. To swivel head, loosen (do not remove) the three socket
head screws with a hex wrench, just enough to allow head to
swivel. (Fig. 2)
5. Rotate head to desired angle, and retighten the three screws.
CAUTION! TO PREVENT INJURY FROM TOOL OR
ACCESSORY FAILURE:
Do not exceed the tool’s maximum air pressure rating.
If the tool still does not have sufcient force a maximum
pressure and sufcient airow, then a larger tool may be
required.
6. To prevent accidents, turn off the tool, detach the air supply, safely discharge any residual air
pressure in the tool, and release the throttle and/or turn the switch to its off position after use.
Clean external surfaces of the tool with clean, dry cloth, and apply a thin coat of tool oil, then store
the tool indoors out of children’s reach.

2. Loosen the three socket head screws that are in the head.
3. Remove the front two screws but do not remove the cutter
head from the tool. (Fig. 4)
4. Remove the old blades making sure that you remember
where each part is placed.
5. Replace the sharpened or new blades making sure they
are returned as they were removed. (Fig. 5)

1. Daily - Air Supply Maintenance:
Every day, maintain the air supply according to the component manufacturers’ instructions.
Maintain the lubricator’s oil level. Use Pneumatic Tool Oil (Order Code A037)
 Drainthemoisturelterregularly.
Performing routine air supply maintenance will allow the tool to operate more safely and will also
reduce wear on the tool.
2. Quarterly (every 3 months) – Tool Disassembly, Cleaning, and Inspection:
 Havetheinternalmechanismcleaned,inspected,andlubricatedbyaqualiedtechnician.
For a full service contact your local Toolmaster service agent.
When not in use, disconnect from air supply, clean nibbler and store in a safe and dry place.
Environmental Protection.
Recycle unwanted materials instead of disposing of them as waste.
All tools, accessories and packaging should be sorted, taken to a recycle centre
and disposed of in a manner which is compatible with the environment.
