TOOL EQUIPMENT AND CARE
In addition to the WARNINGs in this work package, ensure all couplers are wiped clean before
Hydraulic circuit control valve must be in OFF position when coupling or uncoupling hydraulic tools. Failure to do so
may result in damage to quick couplers and cause overheating of hydraulic system.
Always store tool in clean dry space, safe from damage or pilferage.
Ensure circuit pressure hose (with male quick disconnect) is connected to IN port. Circuit return hose (with female quick
disconnect) is connected to opposite port. Do not reverse circuit flow. This can cause damage to internal seals.
Always keep critical tool markings, such as warning stickers and tags legible.
Tool repair should be performed only by Field Maintenance.
Make certain that recommended relief valves are installed in pressure side of system.
Do not use tool for applications for which it was not intended.
Never operate hammer drill without drill bit or without holding it against work surface. To do so, places excessive strain
on hammer drill.
Use sharp drill bits for maximum tool performance. Ensure drill bits are not chipped or rounded on striking end.
Observe all safety precautions.
Install appropriate drill bit for job.
Pull latch at foot of tool so that drill can be inserted into drive hex.
Do not allow your fingers to come between latch and drill steel when closing latch. Failure to
follow this warning may result in injury to personnel.
Push latch back into "latched" (vertical) position to lock bit in place.
Rotation of drill bit is reversible. Drill bit speed is variable in each direction. This is accomplished
by rotating lever on lower section of tool. Tool is in neutral when lever is in vertical up position.
Lever can be rotated 90 degrees to horizontal position in each direction (Direction that bit rotates).
Distance that lever is rotated determines speed of the bit. Horizontal position in either direction is
maximum speed setting.
Drill is not suitable for drilling steel or wood.
Select speed of bit best suited for material being drilled. Most drilling is best accomplished with lever halfway between
fully ON (horizontal) and vertical UP position. Refer to above note.
Squeeze trigger (Figure 1, Item 1) to start the drill. Adequate down pressure is very important.
