Grounding Instructions
This machine must be grounded. If it should malfunction or break down, grounding provides a path of least resis­tance for 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 code and ordinances. Do not remove ground pin; if missing, replace plug before use.
Improper installation of the equipment-grounding
conductor can result in a risk of electric shock. Be sure to
check with a qualied electrician or service person if you
are in doubt as to whether the outlet is properly grounded.
If the plug will not t in the outlet do not modify the plug or
the machine’s cord, instead have a proper outlet installed
by a qualied technician.
This machine is for use on a nominal 120-volt circuit and with a grounding plug similar to the one in Figure 1 below.
If a proper outlet is not available, follow the illustrations of
Figure 2 & 3 to install a temporary-grounding plug. This temporary work-around should be used only until a proper outlet (Figure 1) can be installed by a qualied electrician.
When and if this type of adapter is employed, screw the adapter’s extended tab into place with a metal screw.
However, grounding adapters are not approved for use in
Canada.
Again, be sure to check the grounding pin for damages and replace if necessary.

3.1 - Opening the Unit for Maintenance
To open the Speedster® LTD, loosen the rear latches by
turning them one quarter turn counter-clockwise. Flip the
latches down and then lift up on the push handle and the machine will open up.
3.2 - Filter Maintenance
The Speedster® LTD comes
with a nylon mesh bag lter
that should be placed over
the pump-out lter on the
bottom of the recovery
tank. The nylon bag lter, the pump-out lter, and the solution lter inside the
solution tank should be checked and cleaned on a daily basis.
3.3 - Ball Float Maintenance
The ball oats in the recovery tank prevent recovered
dirty water from rising too high and damaging the vacuum
motors. Clean the mesh screen on the oats regularly.
3.4 - System Maintainer
Weekly ushing of the solution system with Mytee®
System Maintainer helps keep lines clean and prevents chemical build-up, improving pump life, performance and pressure.
How to use System Maintainer:
1. Mix 1-quart 3601 System Maintainer with 1-quart of
warm water.
2. After thoroughly mixing, pour this solution into the solution tank.
3. Turn the pump on FIRST, and run solution through your cleaning tool. NOTE: The jet should be removed from
the cleaning tool in order to prevent clogging due to loosening of deposits in line.
4. Next, turn on the heater (if equipped). If the heater is turned on rst, it will result in a vapor lock, which will aect the machine’s operation.
5. Next, with both the pump and heater on, begin running the solution through the machine. This allows the solution to break down any build up in the lines.
6. After running all of the solution through the machine,
ll the tank with clean, warm water. Run the water
through the machine to clear the solution completely
out of the tank & lines.
