Operating Tips

1.That the more downward force you apply to the tool, the less efficient they are in their operation.

2.Some machines from new may not engage the hammer function and require a solid tap to a hard surface to the tip of a bit which has been fitted to the tool. Rarely would this ever need to be done again

3.When performing overhead work always use the supplied rubber dust chuck cover. Masonry dust is both fine and very abrasive and will finds it’s way into the machines internals and damage the mechanism

4.Ensure you top up the gearbox grease according to the instruction manual. With prolonged use, the internal grease heats up and softens and slowly makes it’s way out through the chuck sleeve.

5.When using the metal chuck adaptor, remember this is for non masonry drilling only! The high impact generated by rotary hammer drills will disintegrate the chuck in a short period of time.
