WARNING
• Wear protective glasses and gloves when working with
batteries.
• Batteries generate flammable hydrogen gas which may
explode. Keep away from flames and sparks.
• Be sure to stop the engine by turning off the starter
switch before inspecting or handling the battery.
• Be careful not to let metal tools (or any metal objects)
such as a hammer or wrench come into contact with the
battery terminals.
• When disconnecting the battery wiring, always discon-
nect it from the earth side (-). When connecting, con-
nect the earth side last.
• Loose battery terminals may cause sparks. Be sure to
fasten terminals tightly.

Removing the crawler
WARNING
When working under the machine while it is raised up, be
sure to use a stand to support the machine.
Important: When replacing crawlers, replace both the
right and left ones at the same time.
1. Lift up the machine.
• Use the blade and hoe attachment to raise the
machine.

starts to come out.
If no grease comes out, slightly move the machine
4
forward and backward.
Check valve: 177 N·m (130 ft.-lb)
3. Insert the iron pipe (3) into the crawler and then ro-

Installing the crawler
1. Lift up the machine, and insert the crawler into the
frame.
• Set the crawler so that it is engaged with the
sprocket.
2. Insert the iron pipe (3) into the crawler and then ro-
tate the sprocket in the reverse direction.
3. Stop rotating the sprocket once the pipe (3) reaches
the side of the sprocket.
4. Slide the crawler into a position where it can be prop-
erly fitted to engage with the idler.
5. Position the crawler so as to ensure that it is securely
engaged with the sprocket and idler and then adjust
