(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.
(13) Adjusting the Chain Wire for Boom
Extension/Retraction and Adding Oil
Caution
⚫
Apply grease to the entire surface of the boom
extension/retraction chain wire once every year
to prevent rust.
⚫
When adjusting the boom extension/retraction
chain wire or adding oil, please contact the
Maruyama dealer near you.
If the boom extension/retraction wire is stretched out,
adjust the chain tension.
With the boom fully extended, rotate the turn buckle to
adjust. (If used with the boom not fully extended, the
wire may be disengaged.) {The target condition is to
have the boom body not touch the chain when it is
extended until it touches the stopper.}
