SPECIFICATIONS AND MAINTENANCE

MAINTENANCE

The rugged and durable Level Best Grader Blade
is built to last, but as with all equipment, a few
minutes of routine care, maintenance, and cleaning
can extend the life of the attachment.
Transport
Various tie-down locations are built into the
GB-108 attachment. Always ensure that your
attachment is properly secured via the DOT proto-
cols of your area.

Cables and Hoses
Check all cables and hoses regularly for signs of
wear and damage. Keep cable connections clean
and free from dirt and corrosion. If a cable has
been damaged, replace it-do not attempt to repair.
Incorrect or poor connections can cause damage to
your electronics or attachment.
When applicable, check the hydraulic hoses. Look
for areas where the hoses could rub against each
other or another object as they expand and contract
under pressure. Check the hydraulic fittings for
tightness.

Machine
Check areas that affect the Automatic Control
system function and accuracy, such as looseness or
play in the cylinders or wear on the box's cutting
edge. Looseness in the connection to the loader,
such as in the adaptor plate will cause inaccurate
depth positioning.
Calibration
Perform periodic calibration checks of the Rotating
Laser System as outlined in its Operation Manual
to ensure accurate performance.
If the Automatic Control System is not functioning
properly, the first step is to determine the problem
component. Use the Troubleshooting Chart to
determine possible causes and remedies. The
following test equipment is needed:
• Voltage/Ohm Meter
• Rotating Laser or Laser Simulator
Cable Wiring Diagrams and troubleshoot electri-
cal problems contact your local Machine Control
Dealer.
Wear Ring, Shims and Wear Pads
The main rotation portion of the Level Best Grader
Blade rides on a non-greaseable oil-impregnated
plastic ring. This ring may wear over time and
shims may need to be removed to ensure a tight fit
Figure 1-21). Periodically check the pads and
(see
main ring for signs of wear or gaps between the pad
and the metal A-Frame. If any are present remove
the 1/16 inch shim (do not discard) by removing
the bolts shown. Do the front and the back, one at a
time ensuring that the bolts are tight before moving
to the other side.
