Operating Instructions
Operation:
Release the reel lock and disengage rewind engagement handle so reel can free spin. Select and install
nozzle, hose guards(s) and roller guides.
Always insert sewer hose several feet into pipe opening before actuating hose reel valve. Never stand in
front of pipe opening when nozzle is near pipe opening. As described in “Setup Section,” work upstream
whenever possible.
You are ready to start pipe cleaning operations after tank filling and engine starting procedures are
followed. Advance engine throttle to full speed.
Note : At this time, put on safety goggles to prevent eye injury from flying water and debris.
Now move hose reel valve ON (up) and let out hose as nozzle pulls into pipe. Untwist hose kinks as
necessary before they enter the pipe. Since it is impossible to know exactly what the nozzle “sees” as it
advances in a pipe, always proceed slowly and cautiously. Pull back 1-2 feet for every 4-5 feet of
progress to make sure that the hose is not burying itself or tying itself up in an open cavity or larger pipe.
Continue working up the line while watching and feeling for speed changes as the nozzle makes its way
into a blockage. When working over a manhole, you often will see dirty water, chunks of grease or debris
flow past as the nozzle penetrates a blockage. When backed up water flows, the line is probably open.
Continue working up the line to open restrictions as desired. Now pull the “working” nozzle back slowly
to re-clean and scour the pipe walls. When working through heavy and long blockages you may have to
flush debris back to machine every 5-10 ft. Repeat until water runs clean from the pipe.
Do not let engine run at full throttle without load (hose reel valve OFF) for longer than 1-2 minutes.
The Model 758 will pull out past 250’ but you will find the going slower because of the pressure loss
from extra hose length. Unless longer operation is common, we recommend the hose extensions be
added only when needed. If moving the jet before the job is done, the hose can be disconnected from the
jet to avoid pulling hose completely out of pipe and restarting.
When finished, turn water valve off (down) before removing nozzle from pipe.
Hint: Wind white tape around hose (a minimum of 6 ft. from end recommended) to warn of nozzle
being to close to pipe opening.
Wind hose back onto reel, remove hose guard and install hose end and nozzle in holder. Put pin in place.
Lock reel. Store all parts in tool box compartment. Follow engine shut down procedure.
Reminder :
Engine key switch must be off to prevent battery drain when not using. Reverse setup instructions, drain
tank and disconnect fill hose. Replace manhole cover or pipe caps and clean up machine before leaving
job site.
