MAINTENANCE PROCEDURES
Keep the vacuum clean, it will have longer life and need fewer
repairs.
When To Change The Oil
To change the oil, follow this procedure:
1. Drain the oil from the engine after the first two hours of use.
2. Fill with 19 ounces of clean oil.
NOTE: See the engine manual for the correct type of oil.
3. After the first change of oil, drain the oil after every 25 hours
of use. Fill with 19 ounces of clean oil.
CAUTION: Never operate the engine when the level of
oil is below the "ADD" mark on the dipstick.
The engine could be damaged.
4. Check the oil level every five hours of use. When the
machine is used in very dirty areas, frequently check the oil
level. If the level of oil is below the "ADD" mark, add oil.
How To Lubricate The Litter Vac
Every fifteen days of use, apply lubricant to the caster wheel
axle, the caster pivot, and the main bushings.
How To Clean The Filter Bag
1. Wash the filter bag when the bag is dirty.
2. Dry the filter bag before using.
How To Check The Tires
Each day inspect the tires on the vacuum. Use a low pressure
gauge to check the air pressure. The air pressure in each tire
must be 35 psi.
Engine Maintenance
Clean the plastic filter and the cooling fins after every 25 hours of
use. The engine manual tells how to clean the filter and the
cooling fins.
The engine used on the Clarke®Litter Vac is a Tecumseh
