1. Clean the casing and terminals.
2.
Lightly grease the terminals to prevent corrosion.
3. Check that connections are tight and tighten if necessary.
Check the battery fluid level.

checked annually. The level should be up to the mark, 0.4 in above the plates.
If a battery casing leaks fluid, the battery must be replaced immediately.

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 fluid level
If the fluid level does not reach the mark -
➤

Winter operation
Batteries are particularly stressed in winter. Only a fraction of the normal starting energy is availa‐
ble at low temperatures.
1.
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.
3. If the machine is to be unused for a number of weeks, remove the battery and store in a frost
