o
Do not force the gear shifter when changing between gears. There is a
neutral position between gear 1 and gear 2.
o
Change gears when the machine is stopped or almost stopped.
Ø
Select and set up fluid delivery method or dust system.
Ø
If using the machine horizontally with the water system, connect hose to the side of
the machine using the connector.
o
This connector takes standard ¾” US garden hose hookup.
o
Make sure the water valve is in the off position.
§
This is generally at a 90 degree angle from the valve hose.
o
Partially turn the water spigot on (usually half a turn).
§
CAUTION: DO NOT turn the hose on fully! You need sufficient water
when using wet type bits. Using too much water pressure can cause
the bits to not cut properly as well as water entering the gearbox.
Ø
Select appropriate size cutting bit and install. See section below for details on
securing bit.
Ø
Check that the machine is firmly attached to the work area.
Ø
Plug the machine into power source.
o
Form a loose knot in the power cord close to the plug connection to prevent
fluid from running down the cord and into the power receptacle.
Ø
Turn feed handle raising the cutter until the bit is above the work surface.
Ø
Open the water valve to allow water to come out to the work surface.
Ø
ATTENTION: BE AWARE THESE MACHINES ARE EXTREMELY POWERFUL. THEY
HAVE A TREMENDOUS AMOUNT OF TORQUE WHICH MIGHT NOT BE SUITABLE
FOR ALL POTENTIAL USERS. ESPECIALLY IN LOW GEAR AND WITH LARGER BITS.
DESPITE THE SAFETY CLUTCH, THESE DRILLS CAN STILL INJURE THE USER. IF IN
DOUBT, CONTACT A PROFESSIONAL FOR ADVICE.
Ø
Turn the machine on by engaging the motor into the “on” position.
o
If wanting the machine to continue in the “on” position, engage the hold
button on the side of the handle above the finger “on” switch. To disengage
the motor when in the hold function, quickly depress the finger “on” switch to
turn the motor off. You may want to cycle through this sequence a couple
times before using the machine for the first time to familiarize the user with
this process.
Ø
Very slowly engage the cutting bit with the material surface by lightly engaging the
hand crank down towards the material.
o
NOTE: During the initial stages of contact the bit may wander.
Ø
After about 1/8” of cutting has been achieved in the work surface, slightly more force
can be applied. This will be the normal amount of force the rest of the hole.
