Husqvarna DS 700, Operator'S Manual

Page: 19 / 24

OPERATION
• After vacuum pressure is verified, machine is
securely held in place, all unauthorized persons
are out of the area, and operator is clear of rotating,
turn Drill Motor Switch (Z) to ON position.
WARNING!
DO NOT contact rotating parts while motor is ON,
or machine is in operation!
WARNING!
DO NOT turn vacuum pump switch OFF while
Drill Motor Switch is in ON position, else drill
stand may move, creating a hazardous situation!
• Verify that the diamond core bit runs true. If the bit
runs eccentrically, it is not properly seated on the
spindle or the bit is damaged. Stop the machine
immediately for repairs.
• Start the water flow using the water control valve
(if motor is equipped). A flow of 1 to 2 gallons per
minute (4 - 8 liters per minute) is usually adequate
to flush material from the diamond segments in a
circular pattern about 1/2” (12mm) around the bit.
• If diamond core bit runs true, and rotates properly,
loosen the Carriage Lock Handle (G) and use
Crank Handle (B) to move diamond core bit toward
the work surface.
• Apply steady, even pressure in the Crank Handle
(B) as it moves into the worksurface. To avoid bit
wandering, apply a light load to start the hole and
wait until the diamond segments penetrate the work
surface before increasing the load.
• Use sufficient pressure so the bit cuts constantly.
Use the Ammeter (DD), if equipped, as a guide for
proper pressure.
• When cut is complete, rotate Crank Handle (B) so
that bit is completely clear of worksurface.
• Tighten Carriage Lock Handle (G) to secure Car-
riage (K) out of worksurface.
• Turn Drill Motor Switch (Z) to OFF position.
• Turn water control valve, if equipped, to OFF posi-
tion.
• After all movement has stopped, unplug machine
from electrical or hydraulic power source. Then,
open the Vacuum Release Valve (EE) to release
the vacuum and allow removal of machine from
worksurface.
NOTICE
If Diamond Core Bit encounters embedded steel,
slow down the feed rate and let the bit operate at
it’s own pace.
To Self-Sharpen, Diamond Core Bits require an
abrasive material. The abrasive material wears
away the metal composition in the segments
metal matrix, thus exposing new sharp diamonds.
DO NOT turn motor OFF until bit is completely
out of worksurface, else bit may become wedged
in work surface!
