2. Placing one wrench on the machined flats of the output shaft and one
wrench on the end adapter of the core bit tighten the bit on the spindle.
Note:
Attempting to turn the bit by the barrel rather than by the adapter nut
may break the weld between the adapter nut plate and the barrel.
When using any Hand Held Drill never hand drill a bit larger than 4” (100 mm)
in diameter. Only use a Drill Stand for drill bits larger than 4” (100 mm) in
diameter.
B. Water Supply:
Always disconnect the power supply before attaching or detaching the
water
system to the Clipper HHD323 Hand Held Drill
1. Attach the Female Quick Coupler to the water supply hose.
NOTE: A
pressure tank can only be used for small hole drilling. The pressure tank
should not be lower than 7 PSI (0.5 bar)
2. Place the Water Valve (Tap) in the “Closed” position
3. Attach the Female Quick Coupler to the Male Quick Coupler by pulling back
on the Female Quick Coupler retaining ring and pressing it gently into the
Male Quick Coupler.
4. Turn on the water supply
5. Slowly turn the Water Tap to the “Open” position
To remove the water supply from the Clipper Hand Held Drill:
1. Slowly turn the Water Tap to the “Closed” position
2. Turn “Off” the water supply
3. Detach the Female Quick Coupler from the Male Quick Coupler by pulling
back on the Female Quick Coupler retaining ring and pulling it gently way
from the Male Quick Coupler.
4. If the job is finished for the day see the section Water System Maintenance
C. Drilling Operation:
The performance of any diamond core bit depends heavily on the use of proper
drilling technique. Although drilling conditions and materials may vary,
following specific guide lines insures faster drilling speeds and longer bit life.
1. Make sure there is no movement in the drill that would cause the core bit to
bind in the hole.
2. Insure that the hole is constantly flushed of abrasive fines by supplying a
sufficient flow of water.
