VIII. SERVICE AND MAINTENANCE

Filters

Engine Air Intake

REMOVAL - The engine air intake filter element should only be removed if it is going to be replaced. After loosening the air cleaner clamp and removing the end cap, carefully remove the filter so as to not knock any dust off the filter and into the air intake passage (fig. 8.14 A and B).

REPLACEMENT - Your sprayer is equipped with a Filter Minder® to notify you of filter element efficiency. Follow its guidelines for servicing. (See below.) At appropriate service time, install the new element carefully to ensure proper sealing.

CLEANING - It is not recommended to clean the air filter element. However, a clean damp cloth should be used to wipe dust and foreign material from the air cleaner housing before a new element is installed.

Filter Minder ®

LOCATION - The Filter Minder® is an air restriction monitoring system that progressively and constantly indicates how much air filter capacity remains. It is mounted at the top of the instrument panel in the cab (fig. 8.15). Check its reading daily.

SERVICE - Service the air cleaner when the Filter Minder® reads 20” (80% of average dirt holding capacity). Reset the Filter Minder® to zero each time you replace the air filter element.

NOTE:

Service the air cleaner before the yellow indicator reaches the red line of the Filter Minder®

VIII. SERVICE AND MAINTENANCE

Grille Screens

In order to maintain maximum air flow through the engine cooling system’s radiator, oil cooler, and air conditioning condenser, the cooling air intake grille screens must be inspected often and periodically removed for cleaning.

REMOVAL - The side grille screens are easily removed by sliding them up out of their housings (fig. 8.16). The top screen is held in place by two bolts (fig. 8.16) and may also be removed for cleaning.

CLEANING - Compressed air will dislodge most large trash or loose dirt after the screens have been removed. Blow out the screens away from the machine. Water from a pressurized hose may also be used, or if necessary the screens may be soaked in soapy water and scrubbed with a brush.

NOTE:

When cleaning cooling fins of the radiator, oil cooler, or A/C condenser with compressed air or water, be careful not to damage cooling fins which may impair cooling capabilities.

Hydraulic Suction Filter

Remove and install a new 10 Micron rated suction filter (fig. 8.17, item 1) at the end of the first 50 hours of use; subsequently, replace the filter every 250 hours, or once a year, whichever comes first.

Hydrostatic Charge Pressure Filter

Remove and install a new 4 Micron rated charge pressure filter (fig. 8.17, item 2) at the end of the first 50 hours of use; subsequently, replace the filter every 250 hours, or once a year, whichever comes first.
