1. Lo w er the loader ar ms , stop the engine , and
remo v e the k ey .
2. Lift/suppor t the side of the unit to be w ork ed
on so that the trac k is off of the g round.
3. R emo v e the loc king bolt and n ut ( Figure 38 ).

4. Using a 1/2 inc h dri v e soc k et ( Figure 39 ), tur n
the tensioning screw counter -cloc kwise until
the distance betw een the tension n ut and the
bac k of the tension tube ( Figure 37 ) is 2-3/4
inc hes (7 cm).
5. Align the closest notc h in the tension screw to
the loc king bolt hole and secure the screw with
the loc king bolt and n ut ( Figure 38 ).
6. Lo w er the traction unit to the g round.

W hen the trac ks are badly w or n, re place them.
1. Lo w er the loader ar ms , stop the engine , and

2. Lift/suppor t the side of the unit to be w ork ed
on so that the trac k is 3 to 4 inc hes (7.6 to 10
cm) off of the g round.
3. R emo v e the loc king bolt and n ut ( Figure 38 ).
4. Using a 1/2 inc h dri v e soc k et, release the
dri v e tension b y tur ning the tensioning screw
cloc kwise ( Figure 38 and Figure 39 ).
