Final Assembly And Test - Briggs & Stratton CE8070 Troubleshooting Manual

Portable Pressure Washer Familiarization and Troubleshooting Guide
Section 4 • Small Frame Electric Pump
CAUTION:
The motor adapter bolt holes line up
with the holes on the piston housing in one position
only. Rotate the motor housing until proper
alignment is achieved.
4. Referring to Figure 4.19, install the three (3) M6-1.0 x 20
socket head cap screws into the mounting screw holes on
the motor housing and thread them into the piston
housing. Because of piston return spring tension, the
motor housing will remain elevated.

Item Name
1 Electric motor
2 SHCS, M6-1.0 x 20mm
3 Piston housing
5. Snug each M6-1.0 cap screw, alternating between screws
until the housings meet. Tighten screws to the torque
value specified in the Torque Chart, found on Figure 4.2
(Exploded View) at the beginning of this chapter.

Final Assembly and Test

NOTE:
Torque the outlet caps at this time, if not
done previously. Verify that all other fasteners have
been torqued to proper values.
1. Position the motor cover housing over the pump
assembly, feeding the two white wires up through the
channel in the housing, as show on Figure 4.1.
2. Insert the bayonet plug into its mating connector in the
housing and switch assembly.
3. Insert the spade connector into its mating spade lug in the
housing and switch assembly.
4. Fasten the housing and switch assembly to the motor
cover housing with four (4) Plastite 6-19 x 0.75" screws.
5. Reassemble the pump into the pressure washer housing,
taking care to avoid pinching wires, etc.
6. Cthe pressure washer to a water supply and connect the
high pressure hose, wand, and spray gun. Connect the
pressure washer to line voltage through a GFCI
receptacle.
7. The pressure washer should provide a spray when the
spray gun trigger is depressed. If the unit does not
produce a spray, the auto switch may need to be
adjusted, as follows:
a. Disconnect the pressure washer from line voltage and
from the water supply.
b. Disassemble the unit so that you can get to the two
taptite screws.
c. Loosen the screws enough to be able to laterally move
the auto switch housing further away from the piston
housing.
d. Tighten the taptite screws to recommended torque
value.
e. Reassemble the unit, reconnect the water and line
voltage and depress the spray gun trigger again.
Normal unit operation should be obtained.
