The housing and the battery connections must not be cleaned with hard objects, e.g. a wire
brush!
The outside of the battery and the terminals should be cleaned regularly with a soft cloth.
This avoids current leaks and minimizes the discharge rate.

1. Open the canopy.
2. Clean the casing and terminals. Do not use a wire brush!
3. Lightly grease the terminals to prevent corrosion.
4. Check that the batteries and cable connections are properly seated and tighten if necessary.

The fluid is generally sufficient for the life of the battery. Nevertheless, the fluid level should be
checked annually. The level should be up to the mark, 0.4 inches above the plates.
Replace the battery immediately if the casing leaks!
1.
Battery destruction!
Topping off with pure acid will increase the electrolyte concentration and can destroy the bat‐
tery.
➤ Top off only with distilled water.
2. Check the electrolyte level.
If the level does not reach the mark -
➤ Top off with distilled water.
➤ Close the canopy.
Winter operation:
Batteries are particularly stressed in winter. Only a fraction of the normal starting energy is availa‐
ble at low temperatures.

Danger of batteries freezing!
Discharged batteries are subject to frost damage and can freeze at 14 °F.
➤ Check battery charge with a specific gravity tester.
➤ Recharge the battery.
➤ Clean the battery terminals and wipe with grease.
2. Check the battery charge weekly.
Recharge as necessary.
