SAFETY PRECAUTIONS
This machine is intended for commercial use. It is
suited to scrub floors in an indoor environment and is
not constructed for any other use. Use only
recommended pads, brushes and cleaning detergents.
The following safety alert symbols are used throughout
this manual as indicated in their description.
WARNING: To warn of hazards or unsafe
practices which could result in severe personal
injury or death.
FOR SAFETY: To identify actions which must be
followed for safe operation of equipment.
The following information signals potentially dangerous
conditions to the operator or equipment:
FOR SAFETY:
1. Do not operate machine:
– Unless trained and authorized.
– Unless operator manual is read and
understood.
– In flammable or explosive areas unless
designed for use in those areas.
– With damaged cord or plug.
– If not in proper operating condition.
– In outdoor areas.
– In standing water.
– With the use of additional extension cords.
Only use manufacturer’s extension cord
equipped with machine which has proper
capacity and is grounded.
2. Before operating machine:
– Make sure all safety devices are in place
and operating properly.
3. When using machine:
– Do not run machine over cord.
– Do not pull machine by plug or cord.
– Do not pull cord around sharp edges or
corners.
– Do not unplug by pulling on cord.
– Do not stretch cord.
– Do not handle plug with wet hands.
– Keep cord away from heated surfaces.
– Go slow on inclines and slippery surfaces.
– Use care when reversing machine.
– Always follow safety and traffic rules.
– Report machine damage or faulty
operation immediately.
– Do not carry riders on machine.
– Follow mixing and handling instructions
on chemical containers.
4. Before leaving or servicing machine:
– Stop on level surface.
– Turn off machine.
– Unplug cord from wall outlet.
5. When servicing machine:
– Unplug cord from wall outlet.
– Avoid moving parts. Do not wear loose
jackets, shirts, or sleeves.
– Block machine tires before jacking up.
– Use hoist or jack of adequate capacity to
lift machine.
– Use manufacturer supplied or approved
replacement parts.
WARNING: Hazardous Voltage. Shock or
electrocution can result. Unplug machine before
servicing.
WARNING: Flammable materials can cause
an explosion or fire. Do not use flammable
materials in tank(s).
WARNING: Flammable materials or reactive
metals can cause an explosion or fire. Do not pick
up.
GROUNDING INSTRUCTIONS
Machine must be grounded. If it should
malfunction or breakdown, grounding provides a
path of least resistance for electrical current to
reduce the risk of electrical shock. This machine
is equipped with a cord having an
equipment–grounding conductor and grounding
plug. The plug must be plugged into an
appropriate outlet that is properly installed in
accordance with all local codes and ordinances.
Do not remove ground pin; if missing, replace
plug before use.

solution tank.
2. Turn on ESswitch. During operation the ES
pump will automatically start recycling when the
ESpump light turns on ( Figure 21 ).
FIG. 21
3. When finished scrubbing, drain and rinse both tanks
and clean ESfilter (See DRAINING TANKS).
WHILE OPERATING MACHINE
WARNING: Flammable materials or reactive
metals can cause an explosion or fire. Do not pick
up.
1. Exercise the SAFETY PRECAUTIONS.
2. Work away from wall outlet and power cord to
prevent cord damage.
3. Observe amount of solution flow on floor. If
necessary adjust to desired flow. See MACHINE
ADJUSTMENTS.
4. Periodically check for foam buildup in recovery
tank (look through clear lid) . If excessive foam is
developing, pour a recommended foam control
solution into recovery tank.
ATTENTION: Do not allow foam or water to enter
ball float screen. Foam will not activate ball float.
Vacuum motor damage due to foam or water is
not covered by warranty.
5. Always operate with caution when scrubbing
around walls or obstacles.
6. If squeegee leaves streaks, raise and wipe blades
with a cloth. Pre-sweep area to prevent streaking.
If squeegee adjustment is necessary, see
MACHINE ADJUSTMENTS.
7. Overlap each pass by 2” (5cm).
8. Change or turn over pads when dirty.
9. Stay clear of floor obstructions, such as electrical
plates or grates, they will destroy pads.
10. During brief stops, simply release triggers and the
