Maintenance - GMC GM18RS Original Instructions Manual

use blades specifically designed for plunge cutting. If in doubt, refer to the blade manufacturer's
instructions.
WARNING: Inspect both sides of the surface you are planning on plunge cutting into. Ensure
there are no foreign objects on the underneath, or objects which could be damaged. Be aware of
hidden pipe work and cables, when plunge cutting into drywalls, ceilings or floor boards. If pipes or
cables may be present, switch off all electrical circuit breakers and shut off water and gas supplies
at the relevant mains valves.
WARNING: Blindly plunge cutting into walls, floors and ceilings may lead to serious injury and
substantial property damage.
1. Mark the line of the cut
2. Choose a point inside the area to be cut out and place the tip of the blade over that point
3. Rest the front edge of the shoe on the workpiece, so the blade does not make contact with the
workpiece surface (main image of fig. VI)
4. Hold the tool securely with both hands by the Main Handle (7) and Barrel Grip (4), and make sure
you have full control at all times
5. Squeeze the Variable Speed Trigger (6) fully, for maximum speed, and allow the blade to reach
full speed
6. Slowly lower the blade until it makes contact with the workpiece
7. Continue to cut slowly, until the blade has fully penetrated the thickness of the workpiece (as
shown in fig. VI)
8. Commence with cutting as normal
Notes:
• Use the same plunge technique when re-entering the same inset cut slot until a section of
material has been removed that allows entry from the edge of the material within the inset cut
• If the technique is unsuccessful, due to the blade or hardness of the material, a more
conventional method will be required for an inset cut as used for metal. Drill a hole or multiple
connected holes wider than the blade and start the cut from the drilled hole
Metal cutting tips
Note: This saw is capable of cutting metals, such as sheet steel, pipe, steel rods, aluminium, brass
and copper.
• ALWAYS use a blade specified for cutting metal
• Be careful not to bend or twist the blade and do not force the cutting action
• ALWAYS use a suitable cutting fluid when sawing soft metals and steel. This keeps the blade
cooler, prolongs blade life and makes cutting more efficient
• Clamp the workpiece firmly and cut close to the clamping point to minimise vibration
• When cutting conduit pipe or angle iron, clamp the work in a vice if possible and cut close to
the vice
• To cut thin sheet metal, sandwich the sheet between hardboard or plywood and clamp the
layers to prevent vibration and tearing of the metal
Accessories
• A range of accessories, including material specific saw blades, plunge cutting blades and other
accessories is available from your GMC dealer. Spare parts can be purchased from your GMC
dealer or online at www.toolsparesonline.com
