BATTERY MAINTENANCE
Charge the batteries each time the machine is used for 1 hour or
longer, or whenever the Battery Meter reads in the red area.
To Charge the Batteries...
1 Remove cover.
2 Plug charger in.
3 Check the fl uid level in all battery cells after charging the batteries.
Add distilled water, if necessary, to bring the fl uid level up to the
bottom of the fi ller tubes.
CAUTION!
To avoid damage to fl oor surfaces, wipe water and acid from the
top of the batteries after charging.
CAUTION!
Acid can spill onto the fl oor if the batteries are overfi lled.
