❏ Cold water supply ( 6 gpm, 5/8", 20 psi)
❏ Hose, wand, nozzle (nozzle size per serial plate)
❏ Water filter (intact, non restrictive)
SET-UP PROCEDURES
1. Put teflon tape on the inlet fitting (about 3 wraps).
Screw on 3/4" garden hose swivel provided in bag.
Attach a 5/8" garden hose to inlet connector. Mini-
mum flow should be 3 gpm.
2. Attach high pressure hose by screwing hose con-
nector to pressure washer outlet, hand tight.
3. Assemble the wand by pushing the two halves to-
gether and then fix by turning the connector to
tighten.
4. Connect wand to trigger gun by turning the connec-
tor. Attach high pressure hose to trigger gun and

5. Remove red oil plug on top of pressure washer and
replace with dipstick supplied. Remove plug from red
oil cap anytime the pressure washer is running.

level in the
sight glass is
at the halfway
level.
