TOOTH REPLACEMENT
Bolt-On tooth points, when worn, can be replaced by
removing the hardware that connects it to the cutting
edge. Install new tooth and replace hardware if nec-
essary. (Figure 5)
Roll-Pinned tooth points, when worn, can be replaced
by driving out the roll pin with a hammer and punch.
Install the new tooth using a new roll pin and hammer.
(Figure 6)
Economical and efficient operation of the backhoe is
dependent upon regular and proper lubrication of all
moving parts with a quality lubricant.
All parts provided with grease fittings should be lubricat-
ed with a good quality chassis lube type grease. If any
grease fittings are missing, replace them immediately.
Clean all fittings thoroughly before using grease gun.
Lubricate all grease fittings at least twice daily, once
at the beginning of operation and again approximate-
ly halfway through the work day.
Lower stabilizers to the ground and lower boom so
bucket rests on the ground as shown in Figures 7
and 8. Refer to these illustrations for the location of
all grease fittings.
IMPORTANT: Before greasing boom to swing
frame pivot (*) shown in Figures 7 and 8, raise
boom and install transport lock pin shown in
Figure 1.
On Models BH650, BH750, BH850 and BH950 the
following locations should be oiled with SAE30 oil:
A. All Control Handle Linkages
B. Seat Bracket Pivot

IMPORTANT: Avoid excessive greasing. Dirt collects on
exposed grease and increases wear greatly. After greas-
ing, wipe off excessive grease from
fittings.
