INSTALLATION INSTRUCTIONS
Safety: Before working on machine stop engine, set park brake, remove key from ignition and block
wheels. Disconnect negative (-) battery terminal.
SWITCH BOX
Mount the switch box to the panel to the right of the operator's seat. Remove the drill screw on the right hand
rear side and mount the Switch Box using this screw. The switch box must be mounted facing towards the
operator's seat.
WIRING
Use dielectric grease on all electrical connections. Connect power cable (15-509) to the switch box. Turn the
switch off. Route the power wire to the fuse block (on the inside of the engine cover) out of the way of any heat
or moving parts. Use nylon ties as needed. Cut the power wire with enough length to connect the fuse block.
Put the slide on terminal with heat shrink onto the wire ends and connect to fuse block. Red to positive(+),
black to negative(-). Insert 10 amp fuse into slot which has red wire attached to it.
CONNECTING THE CAP ASSEMBLY
Connect the blue tube to the tank cap connector which is also connected to the large blue tube which hangs
below the cap. This is the soap outlet tube. Connect the clear tube to the other connector on the tank cap. This
is the air input tube. Tighten connectors hand tight, assembly tank cap onto tank.
HOSES
Being careful not to cut the tubing, cut the oversleeve back approximately 2" (5 cm) to expose blue and clear
tubing. Remove blue wing nut from top connector of foam nozzle and slide it on the blue tube with the threads
facing toward end of tube. Slide blue tube all the way over the top of the small tube on foam nozzle. Slide wing
nut back to the threads and hand tighten. Follow the same steps for the clear tube and tube nut.
Route the tubing along underside of main frame using tie downs as necessary.
Install opposite ends of air-liquid tubes to compressor, again cutting back the oversleeve approximately 2" (5
cm) and inserting blue and clear tubes for the left boom section into the tubing connectors on the right side of
compressor as far as possible. Follow the same steps for the right boom tubing. Notice the right boom is in-
serted into left side of compressor. To release tubing from compressor, hold black ring around tubing, and pull
tube out.
