Pre-Assembly Preparation and Installation
Prepare Drill
Refer to Figure 4
1.
The work may be performed with the drill raised or
lowered. If lowered, the wrench may not be needed,
as the drive shaft cannot rotate.
Identify the location for mounting the meter.
2. If the drill does not presently have a shaft-mounted
acremeter, look for a drive shaft
with a
1 ⁄
2
-20
tapped hole. This is usually the main drive shaft.
Consult your Parts Manual for the factory location of
the acremeter for your drill model.
3. If more than one
1 ⁄
2
-20 tapped shaft end is available,
choose one on the side of the drill customarily
approached for other tasks during operations.
Note: The meter counts (up) rotations in either direction.
It may be installed on the left or right end of any
suitable drive shaft.
Inspect Meter
4. Check that the revolutions configuration is correct for
your drill, see page 2.
5. Check that the units are suitable for your customary
operations.
Note: If the meter fails to display anything, displays
dashes (--------) or is not programmed for your drill,
do not install it. It MUST be programmed before it
is installed. Contact your Great Plains dealer.
Mount Meter
6. Screw the new meter into the shaft hole.
Hand-tighten only. Torque to no more than
15 foot-pounds (20N-m).
Note: If a nut and washer are supplied with the new
meter, these are not used.
