YOUR SWEEPER HAS BEEN SHIPPED COMPLETE, BUT DO NOT ATTEMPT TO OPERATE WITHOUT
READINGAND FOLLOWING THESE INSTRUCTIONS.
PREPARATION
1. Uncrate the sweeper and carefully remove packing material.
2. Inspect the battery connections.
3.^ Fill fuel tank with appropriate fuel.
3.* Install motive power batteries. (See Battery Installation Instructions)
4.* Charge batteries using instructions provided with charger. (See Battery Charging Instructions)
WARNING
Risk of personal injury. Never fill fuel tank while engine is running. Always be sure gasoline container and sweeper
are electrically connected prior to pouring fuel. This can easily be done by providing an insulated wire (Perma-
nently attached to the container) with a battery clip attached to the other end.
4.^ Check engine crankcase oil level.
5.^ Check radiator coolant level. Permanent type antifreeze is added at the factory to provide pro tection
to approximately -35° F (-2° C) To retain this level of protection always add 1/2 part water to 1/2
part antifreeze.
6. Check fluid level in hydraulic reservoir which is located in the engine compartment. The hydraulic
reservoir is full when fluid can be seen in the sight glass on the side of the reservoir. To get an accurate
reading the hopper must be in the “DOWN” position. If fluid is required add HYDRAULIC FLUID ONLY.
Use Ford Automatic Transmission Fluid Type “F”.
