255 SERIES II MM189 (12---89)
TO START MACHINE
NOTE: Before starting machine, perform the pre-start
checks.
1. LPG powered machines: Slowly open the liquid
service valve.
NOTE: Opening the service valve too quickly may
cause the service valve check valve to stop the flow
of LPG fuel. If the check valve stops the flow of fuel,
close the valve, wait a few seconds, and slowly open
the valve once again.
2. The machine operator must be in the
operator’s seat with the directional pedal in the
“neutral” position and with a foot on the brake
pedal or with the parking brake set.
FOR SAFETY: Before starting machine make sure
all safety devices are in place and operate
properly.
3. Gasoline powered machines: When the engine
is cold, pull out the choke knob about
three---fourths of the way. Push choke in after
the engine is running smoothly.
LPG powered machines: When the engine is
cold and exposed to cold temperatures, open
the engine cover, press the primer button on
the LPG vaporizer, close the engine cover.
4. Place the throttle control in to the (Idle)
position.
5. Turn the ignition switch key clockwise until the
engine starts. Do not operate the starter for
more than a few seconds at a time or after the
engine has started.
NOTE: Do not operate the starter motor for more than
10 seconds at a time or after the engine has started.
Allow the starter to cool between starting attempts.
The starter motor may be damaged if it is operated
incorrectly.
6. Allow the engine and hydraulic system to warm
up three to five minutes.
7. Disengage the machine parking brake.
8. Place the throttle lever to the (Fast 1) position
and drive the machine to the solution filling site.
TO SCRUB
Plan the scrubbing in advance. Try to arrange long
runs with minimum stopping and starting. Do an
entire floor or section at one time.
Pick up oversize debris before scrubbing. Remove
bulky debris from aisles before scrubbing. Pick up
pieces of wire, twine, string, etc., which could
become entangled in brush or brush plugs.
Allow a few inches overlap of brush paths.
Do not turn steering wheel too sharply when the
machine is in motion. It is very responsive to the
movement of the steering wheel. Avoid sudden
turns, except in emergencies.
Try to scrub as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine.
Floor conditions, amount of soilage, type of soilage,
brush action, and squeegee action all play an
important role in determining the type and
concentration of detergent to be used. For specific
recommendations, consult the local Tennant
Company Representative.
WARNING: Flammable materials can
cause an explosion or fire. Do not use
flammable materials in solution tank.
The recovery tank should be drained after the
solution tank is empty and whenever the ball float
rises and stops water vacuum. The recovery tank
may fill before the solution tank empties if standing
water is picked up in addition to the solution put
down by the machine.
For best scrubbing results, reduce speed to one-half
maximum machine speed. Shut off solution flow to
floor 5 ft (1525 mm) before making turns. Adjust
solution flow to floor with solution flow knob to match
floor conditions.
Always raise the rear squeegee before backing
machine.
1. Stop the engine and set the parking brake
before filling solution tanks.
FOR SAFETY: Before leaving or servicing the
machine; stop on level surface, set parking brake,
and turn off machine.
2. Open the solution tank covers.
