CHARGING BATTERIES
The following charging instructions are intended for
battery chargers supplied with the machine.
After every 50 hours check the battery charger cord
for damage.
To prolong the life of the batteries only recharge the
batteries if the machine was used for a total of 30
minutes or more. Do not leave batteries discharged
for lengthy periods.
WARNING: Fire Or Explosion Hazard.
Batteries emit hydrogen gas. Keep sparks and
open flame away. Keep battery compartment open
when charging.
FOR SAFETY: When servicing batteries, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
Make sure the charger profile is properly set for the
battery type before charging. Failure to properly set
profile will result in battery damage. To determine the
battery type, see battery label. Contact the battery
supplier if not specified.
To verify the charger profile setting, connect the
charger cord into an electrical receptacle. If the LED
labeled “GEL” is on, the charger is set for Gel
(sealed) batteries. If the LED is off, the charger is set
for Wet/lead acid (flooded) batteries.
To change the charger profile, unplug the charger,
remove the “Charger Profile Selection” panel, and
position the switch towards the proper setting, “GEL”
or “Flooded” .
1. Transport the machine to a well--ventilated area
for charging.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, set parking brake
(if equipped), and turn off machine.
2. If charging wet (lead acid) batteries check the
fluid level before charging (See BATTERY
MAINTENANCE).
3. Remove the battery compartment covers for
ventilation when charging.
