HAV Sprayers
Preparing the HAV for Storage
Preparing the Kubota
®
diesel engine for winter or storage:
Before storing the engine for more than a few months, clean the machine thoroughly and do
ALL of the following:
1. Drain the radiator coolant. Replace with new 50/50 antifreeze coolant.
Since water may freeze when the temperatures drop below 32
O
F (0
O
C), it is very
important that an antifreeze solution is left in the machine.
2. Remove any dirty engine oil and fill with new oil. Run the engine for about five minutes
to allow the oil to penetrate to all the parts.
3. Check all the bolts and nuts and tighten (if necessary).
4. Remove the battery from the engine. Recharge it and adjust the electrolyte level. Store
the battery in a dry / dark place. *When the engine is not used for a long period of time,
run it for about five minutes under “no load” conditions every 2-3 months to keep it free
from rust. If the engine is stored without this running method, condensation from the air
may cause rust on sliding parts of the engine. **If the engine is not run for longer than
5-6 months, apply oil to the valve guide and valve stem sealing and make sure the valve
works smoothly before starting the engine.
Preparing the spraying system for winter or storage:
1. Rinse the entire machine in the application field. Drain the system and flush completely
with fresh water and a solution that will neutralize any liquid mixed according to the
manufacturer’s directions. (Extend
®
works well for many chemicals)
3. Drain the system completely, empty the strainer, run the pump dry momentarily to re
move all excess water. Flush the pump with a 50% solution of permanent type autom-
obile anti-freeze containing a rust inhibitor and water. A rust inhibitor such as Fluid Film
(item number 2160-0010) can also be squirted into the ports of the pump. Turn the shaft
several times to draw the protective liquid through the pump and coat the entire surface.
Drain the pump and plug ports to keep out air during storage. For short periods of
idleness, non-corrosive liquids may be left in the pump, but air MUST be kept out. Plug
the ports or seal port connections.
3. Remove the flow meter at the end of each spraying season. Clean the flow meter
turbine and inlet hub. Clean off all metal filings and wettable powders which have
hardened on the plastic and metal parts. Check the inlet hub and turbine assembly for
worn or damaged turbine blades and bearings.
4. Remove the console from the cab when not in use for extended periods to prevent the
batteries from discharging.
HAV Hydraulic Systems Fluid
Always check the fluid levels before operation. To check the hydraulic fluid level, refer to the
sight glass located on the hydraulic reservoir on the left side center of the HAV. Fluid level
should be through the center of the sight glass when the machine is on flat, level ground. If
the fluid level is below the center of the sight glass, add clean, new hydraulic fluid up to the
center of the sight glass.
Hydraulic Fluid Types:
Shell Donax
®
TD oils are premium quality fluids for use in transmissions, hydraulic systems,
oil immersed brakes and other ancillary systems fitted to agricultural tractors and off-road
equipment. They are exceptional universal tractor fluids specially formulated for use where a
common fluid reservoir serves transmissions, final drives and hydraulic systems.
PBM Supply & Mfg., Inc. recommends you use Shell Donax
®
TD premium hydraulic fluid,
or Mobile-(424) premium hydraulic fluid in the HAV hydraulic system. Contact your local
hydraulic oil distributor to cross reference these fluids if these are not available in your area.
For
severe conditions
, reduce the schedule durations by one-half. Severe conditions are
considered high ambient temperatures, high tractive effort and / or dirty operating environ
