Replacing the Fuel Filters
The sprayer has 2 fuel filters, a threaded filter (located
between the fuel pump and the carburetor) and an in-line
filter (located between the fuel tank and the fuel pump).
Replace the fuel filters after every 400 operating hours.
Replacing the In-line Fuel Filter
1. Set the parking brake, stop the pump, stop the engine,
and remove the ignition key.
2. Clamp off the hose on either side of the in-line fuel
filter to prevent fuel from pouring out of the hoses when
you remove the filter.
3. Place a drain pan under the filter.
4. Loosen and slide the hose clamps away from the filter
(Fig. 36).
5. Remove the filter from the fuel lines.

the filter.
Ensure that the flow direction arrow points toward the
engine.
Replacing the Threaded Fuel Filter
1. Loosen and slide the hose clamp away from the
threaded filter (Fig. 36).
2. Remove the hose from the filter (Fig. 36).
3. Using a 5/16 wrench, remove the filter (Fig. 36).
4. Install a new filter and tighten it until it is secure. Do
not over tighten the filter.
5. Install the hose onto the new filter and secure it with the
hose clamp.
6. Start the engine and check the filters for leaks.
Servicing the Cooling System
Clean the radiator fins of all debris using low pressure
compressed air, water, or a soft brush every 200 operating
hours. Also check all coolant hoses and replace any that are
worn, leaking, or damaged.
Important Do not spray water into the engine
compartment when the engine is hot.
Important Do not add coolant to an overheated engine
until the engine has fully cooled. Adding coolant to an
overheated engine may crack the engine block.
