User Manual

CAUTION: Never attempt to change gears on a running machine! Only adjust when the machine is

at rest.

For 3 speed models, Select the desired gear range by turning the gear selector either clockwise or

counterclockwise into the desired gear. It will usually be necessary to turn the spindle by hand a little to get it

to shift all the way.

For 4 speed models, turn the two gear selectors to the correct combination of A,B,C and D to reach the desired

speed range. (see the chart below).

3 SPEED MODELS RECOMMENDED BIT Ø

Speed 1: n0 450/min, n 280min 200-350mm

Speed 2: n0 810/min, n 485/min 125-200mm

Speed 3: n0 1300/min, n 780/min 20-125mm

4 SPEED MODELS RECOMMENDED BIT Ø

Speed 1: AD n0 385/min, n 225/min 320-450mm

Speed 2: AC n0 530/min, n 300/min 180-320mm

Speed 3: BD n0 975/min, n 565/min 125-180mm

Speed 4: BC n0 1340/min, n 780/min 20-125mm

( Recommended bit size based on average hardness concrete.

Speeds will vary with different material hardnesses.

For reinforced concrete, speeds will be signifigantly slower.)

4)MOUNTING TO A DRILLING STAND (NOT INCLUDED).

Warning: Do not attempt to mount to a rig that does not have a perfectly fitting mounting system.

The motor has a standard four bolt pattern for attaching a mounting spacer. Use a mounting spacer suitable for

the stand you are using to mount your drill motor to your stand. Tighten the four bolts evenly to 12Nm.

To mount to the stand, loosen the cradle lock bolt and place the mounting spacer squarely in the cradle. Then

tighten the cradle lock bolt firmly to 17Nm.

The rig may be anchored to the work piece in one of three ways, with a mechanical anchor, with a vacuum

base, or with a jack screw. (Follow the instructions provided with the rig.)

TO INSTALL THE DRILL STAND

1. Measure the distance from the center of the intended cut to the location of the mounting slot in the

base. Follow the concrete anchor manufacturer’s instructions to install. Using an appropriate tool such

as a rotary hammer, drill a correct sized hole to fit the anchor. Then drive in the anchor to below flush.

2. Move the base into position and screw in the anchor bolt, washer and nut, leaving it finger tight for the

moment.
