SECTION 1: MAINTENANCE
A. INTRODUCTION
This chapter contains instructions for periodic vehicle service and lubrication. These maintenance
actions are scheduled to maintain the vehicle in serviceable condition under normal operating
conditions. If the vehicle is subjected to unusually harsh operating conditions, i.e., dust, extreme heat or
cold, ice, etc, service intervals should be adjusted accordingly. All preventative maintenance must be
accomplished by qualified personnel. Refer to Chapter 5 for specific maintenance instructions for the
powertrain.
CAUTION: FAILURE TO COMPLY WITH THE SCHEDULED
MAINTENANCE ACTIONS AND INTERVALS SPECIFIED HEREIN,
MAY RESULT IN EQUIPMENT FAILURE AND VOID
MANUFACTURER’S WARRANTIES.
B. GENERAL PREPARATIONS FOR USE
1. Battery
Assuming a minimum 80% charge, the duration of usable charge of the MZ battery will vary
from several hours to perhaps a day or more. Variables that affect length of usable charge
include the percentage of initial day’s charge, intensity of use, size and condition of battery,
weight of towed loads as well as environmental factors such as ambient temperature. The
battery should be fully charged before the unit is put into service on a daily basis. For a
complete discussion on battery charging cycles and electrolyte maintenance, see Chapter 1,
Section 6.
WARNING: NEVER TOP OFF CELLS WITH DISTILLED WATER
BEFORE FULLY CHARGING THE BATTERY.
(a) Check the battery fluid level. Top off with distilled or approved drinking water, as
necessary.
(b) If disconnected, connect the battery cables.
2. Brakes
(a) Check master cylinder fluid level, located behind the console panel to the right of the
steering wheel. If low, top off master cylinder reservoir with a high quality brake fluid,
DOT 3 or better.
(b) Service brakes should be tested for pedal firmness and braking effectiveness.
