TIRE PRESSURE
Caution must be used when inflating a low tire to recommended pressure. Over inflating can cause tires to ex-
plode. Front tires and castor wheel should be 20 psi (1.4 bar), rear tires should be 18 psi (1.3 bar) maximum.
Improper inflation will reduce tire life considerably.
ENGINE OIL
Change and add oil according to charts below. Do not overfill. Use a high quality detergent oil. For Briggs engine
use oil classified “For Service SJ or higher” SAE 30 oil. For Kubota Diesel engine use oil classified “For Service
CC, CD or CE” API oil. Use no special additives with recommended oils. Do not mix oil with gasoline.
SAE 30 oil, if used below 40° F (4° C), will result in hard starting and possible engine bore damage due to inad-
equate lubrication.
The use of non-synthetic multi-viscosity oils in temperatures above 40°F (4° C) will result in higher than normal
oil consumption. Check oil level more frequently when using a multi-viscosity oil.

TOWING
When it is necessary to move the Sweep Star 60 without engine running, the bypass valve built into hydrostatic
pump must be “open” by turning it counterclockwise. The valve is located on bottom left of pump. An “open” valve
allows fluid to pass through the wheels freely. When normal, driven, operation is desired, valve should be closed
by turning it clockwise. Failure to “close” the valve with engine running means no power to wheels.
BATTERY
Batteries normally produce explosive gases which can cause personal injury. Do not allow flames, sparks or any
ignited object to come near the battery. When charging or working near battery, always shield your eyes and
always provide proper ventilation.
Battery cable should be disconnected before using “Fast Charge”.
Charge battery at 15 amps for 10 minutes or 7 amps for 30 minutes. Do not exceed the recommended charging
rate. If electrolyte starts boiling over, decrease charging.
Always remove grounded (-) battery clamp first and replace it last. Avoid hazards by:
1. Filling batteries in well-ventilated areas.
2. Wear eye protection and rubber gloves.
3. Avoid breathing fumes when electrolyte is added.
4. Avoid spilling or dripping electrolyte.
Battery Electrolyte is an acidic solution and should be handled with care. If electrolyte is
splashed on any part of your body, flush all contact areas immediately with liberal amounts
of water. Get medical attention immediately.
FILTER PACK
Filter pack may be cleaned by shaking or spraying off with low pressure water. Filter will disintegrate if high
pressure is used on it.
