HAV Sprayers
Starting the HAV
Ignition Switch Positions
PREHEAT
Warms the glow plugs.
OFF
Shuts off the engine and all accessories. Key may only be removed from Off position.
ON
Enables operation of all electrical accessories and allows the engine to continue
running after initial start.
START
Cranks the starter motor. Key position must be released immediately when
engine starts to prevent damage to starter. Spring-loaded to enable the switch to
return to the ON position when released.
Step 1, Pre-heat the Engine
For Diesel models, In cold temperatures it is necessary to pre-heat the engine before start-
ing. Pre-heat by turning the ignition switch to the left and holding until the orange indicator
light turns off.
Step 2, Turn the ignition switch to “ON”
and press the oil pressure cut-out bypass switch (located on gauge panel) at the same time.
Step 3, Turn the ignition switch to “START”
until the engine starts, then immediately release the switch. Release the ignition switch if
the engine does NOT start within 10 seconds. Prolonged cranking of the engine without
starting it may damage the starter motor.
Step 4, Watch the oil pressure gauge
until the pressure exceeds 10 PSI, then release the oil pressure cut-out bypass switch.
If the oil pressure does not register or does not rise above 10 PSI within several sec-
onds, shut down the engine immediately and check for any of the following problems: Is the
engine oil level too low? Does the engine oil have dirt in it? Is the oil pressure gauge hose
faulty? Is anything causing the low oil pressure Murphy switch, or water temperature Murphy
switch to kill the engine?
Step 5, Adjust the engine speed to desired RPM
Shutting Down the HAV
1. Return the throttle lever to the lowest idle position.
2. Turn the ignition key to the “OFF” position.
3. With the ignition in the “OFF” position, it is now safe to remove the key.
Jump Starting the HAV
If the HAV cannot be started because the battery is out of charge, it can be jump started
from another battery.
NOTE: Batteries produce explosive gases and other explosive
fuels may be present during the jump starting process.
Keep sparks, flames and smoking
materials away from the battery at all times.
1. Use high quality jumper cables and make sure all connections are clean and solidly
connected.
2. Wear proper eye protection before attempting a jump, in case of acid contact with skin,
eyes or clothing.
If Accidental Contact Does Occur, Flush Immediately With Water For
ONE Full Minute And Seek IMMEDIATE Medical Attention.
3. Connect positive (+) terminals first. Be sure to NOT cross the cables while making
connections.
Do NOT allow contact between the cable clamps while making connection.
4. Connect one end of the ground cable to the ground (-) terminal on good battery first.
Then connect the other end of the ground cable to a solid, bare-metal connection on the
engine.
Do NOT connect to the negative (-) terminal of the battery.
5. Start the engine.
6. Disconnect the ground cable at both ends before disconnecting the positive (+) cable.
