the engine is running. Failure to check  
the oil level before you use the machine  
can destroy the engine. Always make  
surethemachinehasthecorrectamount  
of oil.  
Follow this procedure to check the oil:  
1. Make sure the machine is on level ground.  
2. Turn the cap marked "Engine Oil" counterclockwise.  
3. Lift the dipstick out of the tube.  
4. If the mark is below "OK", add oil.  
5. Whenaddingoil,makesuretheoildoesnotpassthemark  
"FULL" on the dipstick.  
See the engine manual for the correct type of oil.  
HOW TO FILL THE GASOLINE TANK

How to Prepare The Machine for Operation  
Model SPS-28B - Battery Powered  
1. Before starting the SPS-28B lift the battery box cover and  
make sure the battery cables are connected.  
2. Place all controls in "NEUTRAL".  
3. Turn OFF/ON switch to "ON" position. (Switch is located on  
left side, below hourmeter.  
NOTE: The OFF/ON switch is also a circuit breaker which  
senses overload on the drive motor and breaks the circuit.  
Should this occur, determine the cause of the overload  
(e.g., remove the debris jamming the main broom) and  
turn the circuit breaker back to the "ON" position.  
HOWTOCHARGETHEBATTERIES  
Put the charger on a flat surface. Make sure the vents on  
the sides of the charger are at least two inches away from  
the walls and other objects. Make sure there are no  
objects near the bottom vents of the charger.  
To charge the batteries, follow this procedure:  
1. Turn the machine OFF.  
2. Connect the DC connector on the charger to the  
connecting plug on the batteries. See Fig. 1  
3. Connect the AC plug on the charger to a receptacle  
that has the correct voltage and frequency for your  
charger. Make sure the receptacle is connected to  
the electrical ground.  
Fig. 1  
4. The electronic timer stops the charger when the  
batteries are fully charged.  
See the instruction book for the charger, and for more  
instructions on how to use the charger and charge the  
batteries.

forthesidebroomisgenerallyhavingaboutone-thirdofthe  
bristles engaged with the floor in "SWEEP" positon.  
3. To change the angle of the broom, to the floor, loosen the  
knob and rotate the head assembly until the desired anfle  
is obtained.  
To change the height of the side broom, i.e., (1) lower or more  
bristle contact; (2) higher or less bristle contact, follow these  
instructions:  
1. Lower the broom assembly to its engaged position and  
be certain the locking pin is in its slot on the collar.  
2. Loosen the two socket head screws which lock the split  
collar to the tubular bumper.  
3. Swivel the collar until the correct height is obtained. Hold  
inthisposition,maintainingtensiononthesidebroombelt,  
and tighten the two screws to lock the collar.

Accordion Type Cloth Filter (Optional)  
To insure continued maximum efficiency of the dust control  
system on your sweeper, the cloth type filter should be  
frequently shaken (See Fig. 6) using the handles provided.  
The dustier an area is, the more often the shakedown should  
be done. The dust hopper should then be emptied.  
How to Clean the Cloth Filter  
Remove filter assembly from the machine. Direct com-  
pressed air through material opposite the normal air flow  
direction. (See Fig. 7)

SHOPEVALUATIONOFCHARGERS  
(QualifiedServicePersonnelOnly)  
Service Hints  
1. Check the AC power supply (plug, cords, building  
fuses and switched, etc.)  
2. Check for physical damage.  
3. If there is no DC output, check for blown internal  
fuse(s);blownfusesmaybecausedbyreversedDC  
connections or by a defective diode.  
4. Checkparts-ammeter,timer-switch,diodes,trans-  
former and fuses for tight connections and for  
discoloration due to electrical failure.  
WARNING: Always wear eye and face shield,  
and protective clothing when  
working with batteries to avoid  
injury.  
5. Check the condition of the batteries.  
a. Specificgravity(1.280isidealforfullycharged  
batteries.  
b. The battery bank voltage should come up to  
about 30.7 volts at the end of the cycle.  
c. The DC charging current should start in the  
"normal" range and end in the "finish" range.  
If the charger is still inoperative after the above checks  
have been made, call your nearest authorized service  
center.

Capacitor Test  
If a commercial capacitor checker is not available, the  
following test may be made:  
1. Briefly short the capacitor terminals together with a  
screwdriver.  
2. Disconnect a wire from either capacitor terminal.  
3. Adjust an ohmmeter to a high value such as RX10K or  
RX1 Meg.  
4. Connect the ohmmeter leads to the capacitor terminals.  
5. A good capacitor will cause the indicator to move quickly  
to zero ohms, then slowly return to infinite ohms. An  
open capacitor will not cause any indicator movement; a  
shorted capacitor will give a continuous zero ohms  
reading.  
6. If the test is to be repeated, the capacitor terminals must  
again be shorted together briefly.  
Diode Test  
1. You must have a #308 ct. Everready continuity tester or  
equivalent/  
2. Desolder both wires from the diode lead connections.  
(Clamp heatsink pliers on the diode leads to avoid  
damaging the diodes.)  
3. Attach one of the test unit leads to either diode lead.  
4. Attach the other test unit lead to the diode heatsink.  
5. Turn the test unit on and note if the test unit bulb lights.  
DANGER:  
Reversing charge or polarity of wiring  
couldcausebatteriestoEXPLODEcaus-  
ing serious bodily harm to yourself or  
others.  
6.. Reverse the test unit leads in Steps 3 and 4.  
7. Turn the test unit on and note if the test unit bulb lights.  
8. Good diode - test light bulb should light up in one of  
Steps 5 and 7 and not in the other.  
Defective diode - test bulb will light up in both  
Steps 5 and 7.  
Defective Diode - Test bulb will not light up in either  
Steps 5 or 7.
