**

If your machine shipped with batteries installed do the following:

• Check that the batteries are connected to the machine (7).
• Turn ON the Key Switch (A) and check the Battery Indicator (B). If the green light is ON, the batteries are ready for use. If the green light is OFF, the batteries should be charged before use. See the “Charging The Batteries” section.

If your machine shipped without batteries installed do the following:

• Consult your Authorized Nilsk S/A dealer for recommended batteries.
• Install the batteries by following the instructions below.
• DO NOT install three 12-volt batteries in your machine. This affects the stability of the machine.

WARNING!
Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin or eyes. Explosive hydrogen gas is vented from the batteries through openings in the battery caps. This gas can be ignited by any electrical arc, spark, or flame. Do not install any lead-acid battery in a sealed container or enclosure. Hydrogen gas from overcharging must be allowed to escape.
When Servicing Batteries…
Remove all jewelry
Do not smoke
Wear safety glasses, rubber gloves, and a rubber apron
Work in a well-ventilated area
Do not allow tools to touch more than one battery terminal at a time
ALWAYS disconnect the negative (ground) cable first when replacing batteries to prevent sparks.
***** ALWAYS connect the negative cable last when installing batteries.

CAUTION!
Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Norilsk S/A, a qualified electrician, or the battery manufacturer should install batteries.

1. Remove the batteries from their shipping crate and carefully inspect them for cracks or other damage. If damage is evident, contact the carrier that delivered them or the battery manufacturer to file a damage claim.
2. Turn the Master Key Switch (A) OFF and remove the key.
3. Open and prop the Battery Compartment Cover (13). Remove the battery cables from inside the battery compartment.
4. Your machine comes from the factory with enough battery cables to install six 6-volt batteries. Carefully lift the batteries into the battery compartment and arrange them exactly as shown in FIGURE 1. Secure the batteries as close to the back of the machine as possible.
5. Install the battery cables as shown. Position the cables so the battery caps can be easily removed for battery service.
6. Carefully tighten the nut in each battery terminal until the terminal will not turn. Do not over-tighten the terminals, or they will be very difficult to remove for future service.

2. Place your hand underneath the Dust Control Shroud (2) and remove the Pad Retainer (4) from the flexible pad holder assembly. NOTE: Grip the retainer firmly and turn clockwise (to the right) as the retainer uses a Left Hand thread.
3. Select a 27 inch (68 cm) Dia. Burnishing Pad (AA). See your local Nilsk S/A Distributor for a complete selection of pads and accessories.
4. Insert the plastic Pad Retainer (4) into the center of the Pad (AA). Then reinstall by turning the retainer counter-clockwise (to the left).
   NOTE: Important !!! Turn the retainer in until you hear a clicking ratchet sound, this insures proper tightening of the pad by properly compressing the pad material and drawing up the retainer so it will not strike the floor.

INSTALLATION OF THE DUST COLLECTION BAG
The UHR70-1700 uses dust collection bag PN 56391185 (sold 6 to a Package).
See Figure 3. Unfold the Dust Collection Bag (5) and while holding onto the Card Board Retainer (AA) insert it over the Collection Tube (BB) found on the top of the Pad Drive Deck (1) on the left side of the machine.
NOTE: Never operate the UHR70-1700 without a Dust Collection Bag (5) or the optional Active Dust Control Kit (21) PN56422083 installed. Failure to do so will allow the burnishing dust to become airborne. The Active Dust Control Kit (21) is running whenever the Master Key Switch (A) is ON, the Pad Drive Deck (1) is down and the FWD/REV Drive Pedal (8) is off the neutral position.
Extra Dust Collection Bags can be stored in the Spare Dust Bag Storage (18) box as shown. Install the Rubber Strap (CC) as shown to secure the bags.

BEFORE EACH USE:

1. Be sure you understand the operator controls and their function.
2. Turn the Master Key Switch (A) ON (l) and check the Battery Condition Indicator (B). If the red light comes on, recharge the battery pack before using the machine
3. Check that a new or clean pad has been installed.

PLAN YOUR FLOOR BURNISHING:

1. Pre-sweep or scrub floor area of debris to prevent scratching and poor burnishing performance.
2. Arrange long runs with a minimum of stopping or starting.
3. Avoid bumping into posts or scraping the side of the machine.

OPERATING THE MACHINE

NOTE: Bold numbers or letters in parentheses indicate an item shown on pages B-6 – B-7.
Follow the instructions in PREPARING THE MACHINE FOR USE and the BEFORE EACH USE section of the manual.

1. While seated on the machine adjust the Steering Wheel (11) using the Tilt Steering Wheel Adjuster (9), to a comfortable operating position.

2. Turn the Master Key Switch (A) ON (l). This will display the Battery Condition Indicator Light(s) (B) and Hour Meter / Error Display (C).

3. To transport the machine to the work area, apply even pressure on the front of the FWD/REV Drive Pedal (8) to go Forward or the rear of the pedal for Reverse. NOTE: The front drive wheel has a built-in electromagnetic brake that engages whenever the FWD/REV Drive Pedal (8) is in the neutral position or when the Master Key Switch (A) is turned OFF. See the ELECTROMAGNETIC BRAKE section for manual override instructions.

4. Once at the work area, the pad pressure can be adjusted by turning the Master Key Switch (A) off. Hold down the Pad Drive Raise / Lower Switch (E) while turning on the aster Key Switch (A). The word “Adjust” will scroll on the Display (C) and the Pad Drive Raise/Lower Switch can be released. Once released, the display will read either “1”, “2”, or “3”. These are the pad pressure settings with “3” being the highest pad pressure setting. To change pad pressure, press the Pad Drive Raise / Lower  Switch (E) to increment between 1, 2, and 3. Once you have selected the setting that you want to burnish turn the Master Key Switch (A) off to store the setting in the memory. This setting will remain in the control panel’s memory until it is changed again using the above procedure.

5. When at the work area press the machine’s FWD/REV Drive Pedal (8) to move the machine to either FWD or REV drive. The machine should always be moving before lowering the Pad Drive Deck (1).

6. Once the machine is moving, lower the Pad Drive Deck (1) by pressing the Pad Drive Raise / Lower Switch (E). The Pad Drive Indicator Light (D) on the control panel will light yellow when going down and then turns green to con rm the lowered position and the pad begin to turn. To raise the Pad Drive Deck (1) press the Pad Drive Raise / Lower Switch (E). The Pad Drive Indicator Light (D) will be red when coming up and then turns OFF to confirm the raised position. NOTE: When the operator’s foot is removed from the Drive Pedal, the pedal automatically returns to neutral and the pad motor will shut off after about 1 second (the Pad Drive Indicator Light (D) will light yellow). Raise the Pad Drive Deck before stopping the machine. The floor may be damaged if the machine is stopped with the pad down and running.

7. Begin burnishing making long straight line passes, and overlap each pass 2-3 inches (5-7 cm). Adjust your machine speed according to the condition of the floor (if the floor is heavily scuffed, drive at a slower rate to ensure proper burnishing). The Active Dust Control Kit (21) if installed will be running whenever the Master Key Switch (A) is ON, the Pad Drive Deck (1) is down and the FWD/REV Drive Pedal (8) is off the neutral position.
   **CAUTION!**
   The floor may be damaged if the travel of the machine is stopped with the pad down and running.

8. It may become necessary when burnishing to stop the machine, raise the pad and check to see if the pad is loaded up with floor finish and dirt. If it is, turn the pad over to expose the clean side, or install a clean pad.
