120 VAC GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should electrically malfunction, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This appliance 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 and grounded in accordance with all
local codes and ordinances.
WARNING!
The machine must be used with an extension power cord as follows:
minimum length 15 feet
type S, or ST, or SO, or STO, or STW
minimum rate 300V 140/167°F (60/75°C)
–
–
–
DANGER!
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a
qualied electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify
the plug provided with the appliance. If it will not t the outlet, have a proper outlet installed by a qualied electrician.
This appliance is for use on a nominal 120 V circuit, and has a grounding plug that looks like the plug (B, Fig. 1). A
temporary adapter (B and C) may be used to connect this plug to a 2-pole receptacle (B), if a properly grounded outlet
is not available. The temporary adapter should be used only until a properly grounded outlet (A) can be installed by
a qualied electrician. The green-colored rigid ear, tab, or the like extending from the adapter must be connected to
a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in
place by a metal screw. Grounding adapters are not approved for use in Canada.
Replace the plug if the grounding pin is damaged or broken.
The Green (or Green/Yellow) wire in the cord is the grounding wire. When replacing a plug, this wire must be attached
to the grounding pin only.
Extension cords connected to this machine should be 12 gauge, three-wire cords with three-prong plugs and outlets.
DO NOT use extension cords more than 50 feet (15 m) long.

BATTERY CHARGING [MICROMATIC M17B]
NOTE
Charge the batteries when the warning light (3) or (4) turns on, or when nishing cleaning.
Keeping the batteries charged makes them last longer.
CAUTION!
When the batteries are discharged, charge them as soon as possible, as that condition makes them last shorter.
Check for battery charge at least once a week.
WARNING!
When using lead (WET) batteries, battery charging produces highly explosive hydrogen gas. Charge the
batteries in well-ventilated areas and away from naked ames.
Do not smoke while charging this type of batteries.
During the charging of this type of batteries, the recovery water tank (A) must be removed.
WARNING!
When using lead (WET) batteries, be extremely careful while charging the batteries as there may be battery uid
leakages. The battery uid is corrosive. If it comes in contact with the skin or eyes, rinse thoroughly with water
and consult a physician.
CAUTION!
Batteries must be charged indoors, in a dry environment (damp free).
Preliminary procedures
Drive the machine on a level ground.
Check that the switches (5 and 6) are turned to “0”.
If there is recovery water in the tank (43), drain it through the hose (22).
For lead (WET) batteries only:
Disconnect the vacuum hose (29) from the squeegee (17).
Open the cover (12).
Grasp the recovery water tank (A) in the area (B) and lift it, as shown in the gure, then disconnect the vacuum hose (C)
from the tank and remove the tank (A) together with the hoses (D) and (E).
Check for the correct level of electrolyte inside the batteries (50). If necessary, add distilled water through the caps.
Leave all the battery caps open for next charging.
If necessary, clean the upper surface of the batteries.
Charge the batteries according to one of the following procedures, depending on the presence of the battery charger (33).
