Water System
Use extreme caution when
operating the machine on slopes,
as it is more susceptible to sideways
tipping/rolling over, especially with
a full water tank.
The water system cools the core bit and flushes
slurry from the drilling hole. Note: Always test the
water supply for adequate pressure and flow prior
to drilling.
Filling the Water Tank
Filling the Water Tank
1. Remove the water tank cap(s) and fill the tank
with water as necessary. Note: The clear hose at
the rear of the tank indicates the water level.
2. Replace the cap(s) when finished.
Using the Water Supply
1. Open the water valve directly under the water
tank. DO NOT confuse this valve with the water
release valve, which is located near the side of
the tank.
2. Turn on the Water switch.
3. Open the water valve.
4. Adjust the water flow valve to increase or
decrease water flow to the core bit. Note: Using
too much water when drilling will make the slurry
look clear. Not using enough water will make
the slurry look thick and pasty, and could result
in a stuck bit.
5. Use the attached water hose for cleaning or
other tasks as needed. This hose functions as a
typical garden hose. Note: Turn on the master
battery disconnect to use the water hose with
the engine off. DO NOT drain the battery.
6. Decrease the water flow and close the water
valve when finished.
7. Turn off the Water switch. Note: Always turn off
this switch when finished drilling to avoid
draining the battery.
NOTE: Too much water makes the slurry look clear
and waste water, insufficient water makes slurry
thick and can result in a core sticking in bit.
Draining Water System
1. Be certain the area is safe for draining
water.
2. Open large valve located on the front right
side of machine.
3. Complete draining is only required in areas
where temperatures result in freezing, or
machine is going to be stored for a long
period of time.
Vacuum System
DO NOT stand on the
machine to act as an
anchor. Use the vacuum
pump to anchor the
machine.
The vacuum system is only used during the drilling
operation when the base is firmly on the ground;
this adds stability to the system and should be used
whenever possible. Cleaning and wetting the
surface with the garden hose helps to ensure a
proper seal.
Using the Vacuum
1. Turn on the circuit breakers.
2. Close the vacuum valve on side dash.
3. Turn on the Vacuum switch.
4. Open the vacuum valve to release suction
when finished.
5. Turn off the Vacuum switch.
Vacuum Gauge
The vacuum gauge indicates that the vacuum
system is working. Vacuum pressure should max out
at 25” Hg. Note: Poor vacuum suction may indicate
loose hose fittings; loose water trap jars; worn
vacuum base seals; or the base may be placed
over a cracked/scored surface where suction is not
possible.
