(11) Adjusting the Belt Tension
[1] Engine
HST
Loosen the hexagonal bolt and twist the main body
until the tensioner mounting angle becomes 15
.
After the adjustment, tighten the hexagonal bolt
loosened earlier, to a torque of 43 to 53 N
m.
[2] Engine
dynamic injection
Make adjustment so that when the center of the
belt is pressed with a force of 15 to 19 (N), the
amount of deflection becomes approx. 5 mm.
(12) Inspecting the Battery
Warning
Do not use or charge the battery when the
battery fluid level is low, because the battery
may rupture (explode) or ignite.
Caution
When inspecting the battery terminals, do not
let the terminals get short-circuited.
When disconnecting the battery cable, be sure
to disconnect the negative terminal end first.
Battery fluid is very corrosive, so do not spill
the fluid. If battery fluid attached to your hand,
clothes or any metal part, rinse the affected
area thoroughly with water.
Maintenance-free battery
The battery without top cap is a maintenance-free
battery.
[1] Look at the charge indicator vertically.
[2] If the charge indicator is clear or yellow, gently tap
the battery to remove air bubbles and then check
again.
[3] Take an appropriate action according to the table
below based on the indicator color.
Color
Charge state
Action
Green
Normal
The battery can be used.
Black
Insufficient
Auxiliary charge is
required.
Clear
Not enough
fluid
Replace the battery if the
engine does not start.
* There is no need to inspect the battery at the start of
work.
Conventional battery
[1] Check if the battery fluid level is between UPPER
and LOWER. If the level is low, add distilled water
to the UPPER level.
[2] After distilled water has been added, securely
tighten the cap.
[3] Inspect the battery terminals and if loose, securely
tighten the terminals. If white powder is attached to
the terminals, clean with hot water and tighten the
terminals, and then apply a small amount of
grease on the terminals.
Caution
Do not continue using the machine once the
electrolyte level in the battery has dropped to or
below the lower limit (LOWER level) indicated
on the side face of the battery. Deterioration of
each part of the battery cell will be promoted.
Adjust to this 15
line.
