Maintenance - GMC GSDS800 Manual

Drilling metal
• Use Drill Mode (A) only
• To ensure accuracy, mark the intended hole position using a hammer and centre punch
• Ensure that drill bits are suitable for the grade of metal being drilled, and are within the
maximum diameter capacity of the drill
• To ensure efficient cutting, and prolong drill bit life, use a suitable lubricant/cutting fluid
CAUTION: Applying excess pressure does not result in faster or more efficient drilling. If the
pressure applied to the drill has a noticeable effect on the speed of the drill then reduce the
pressure. Overloading the drill will reduce its service life.
• As the drill bit penetrates the material being drilled, it may 'catch' or 'snag'. This can cause
the machine to suddenly 'kick', to prevent any possibility of injury always hold the drill
securely, use the Auxiliary Handle (10), and use sharp drill bits
• Always ensure material is secure. If appropriate use a vice or clamp to hold the work,
always keep two hands on the drill
Accessories
• A range of accessories for this product are available from your GMC dealer including SDS
Plus drill and chisel bits. Carbon brushes are available from www.toolsparesonline.com or
your GMC dealer.
