Procedures for Loading, Transporting, and

Page 6 of 30

Unloading Battery Burnisher

DANGER: The machine is very heavy, so be very careful when loading,

transporting, and unloading the machine. Use at least two people to load or unload the machine.

• Loading Procedure Using a Ramp a) It is not recommended that the battery burnisher be loaded using a ramp with

an incline of more than 7 degrees. The machine is not self-propelled and therefore it is not able to assist itself up a ramp. It is too heavy to manually push up a steep incline.

b) If you must load with a ramp, the incline must be no more than 7 degrees. (This

would permit a height of no more than one foot for an 8-foot ramp). c) Ramp must be secured to vehicle, and be clean and dry. d) Machine must be pushed or pulled straight up the ramp and never at an angle.

• Loading Procedure Using a Lift Gate a) Lift gate must have ample capacity to lift the burnisher. b) Wheels must be firmly chocked to prevent burnisher from rolling off the lift gate.

• Securing Battery Burnisher a) Burnisher must be secured, so that it will not roll or turn over. Use chocks and

tie downs to secure.

b) Please be aware that the battery burnisher is very heavy, and that a metal

bulkhead in a van may not contain equipment in the event of an accident. The equipment in a van can be more dangerous than the accident itself.

• Unloading Procedure Using a Ramp a) Ramp must be long enough so that removal can be controlled. Use same ramp

incline restrictions as used for loading burnisher. b) Ramp must be secured to vehicle, and be clean and dry. c) Machine must be taken straight down the ramp and never at an angle. d) Do not let machine run over you or anyone else as it comes off ramp.

Page 10 of 30

OPERATION

• PLUG THE CORD FROM THE CHARGER INTO A 110 VOLT OUTLET

• Batterie s should now start charging.

• A test is run o n the battery voltage to decide if the charging process should be started or not. If the

battery is not connected to the battery charger, the display will show the word “bat”. The word will stay on, even if the test is failed (for instance, reversed polarities or incorrect battery connection). If the test is passed, the display will show the battery voltage for approximately 5 seconds and the battery will begin to be charged. The charging cycle progress will be shown by red, yellow, and green LED indicators. At the end of the charge, when the green indicator is on, unplug the cord from the socket and operate the machine.

• NOTE: THE MACHINE WILL NOT POWER ON IF THE CHARGER IS STILL PLUGGED IN TO THE 110 VOLT OUTLET.

INDICATOR LIGHTS

• Red indicator shows that the charging cycle has started.

• Yellow indicator shows that the final phase of the charging cycle has

started.

• Green indicator shows that the charging cycle has finished.

DISPLAY

Press button “S” (for Selection) to display:

• A = the charging current,

• U = the batte ry voltage,

• h = the charging time,

• C = the charging ampere-hours [Ah],

• E = the energ y used [KWh].

CAUTION - CHARGER SETTINGS MUST BE CHANGED IF BATTERY TYPE IS CHANGED (SEE NEXT PAGE FOR SETTINGS)

THIS BATTERY CHARGER IS FACTORY SET FOR THE TYPE OF BATTERIES THAT CAME WITH YOUR MACHINE. IF YOU SWITCH BATTERY TYPES (FOR EXAMPLE GO FROM AGM TYPE BATTERIES TO STANDARD WET CELL BATTERIES), THEN THE BATTERY CHARGER MUST BE REPROGRAMMED. SEE NEXT PAGE “HOW TO SET THE CHARGER FOR DIFFERENT SIZES AND TYPES OF BATTERIES” FOR INSTRUCTION.

GENERAL INFORMATION AND WARNINGS

• READ SAFETY INSTRUCTIONS ON PAGES 4 AND 5

• This is a state-of-the-art electronic high frequency automatic battery charger with microprocessor.

• It is suitable for any battery type, if the charger has the proper settings. (Call manufacturer of

machine on how to set the charger for different batteries than were supplied with your machine)..

• Never disconnect the battery while charging, since this could cause sparks.

• Never use the equipment in the rain, in areas used for washing, or in wet or damp areas.

• Use battery charg ers only in well ventilated areas.

FOR LEAD ACID BATTERIES:

• Control the water level after each ch arging process. (See “Battery Maintenance” page).

• Refill with distilled water only.

• Caution! The gases generated during charging are explosive. Do not smoke in the vicinity of the

batteries. When working with cables and electrical equipment, avoid open flame s and sparks.

• Attention: Use prote ctive glasse s and gloves during battery maintenance. Battery acid causes injuries. In case of contact with battery acid, wash the affected parts with a lot of fresh water and consult a doctor if necessary.

BDI DISPLAY

When the machine is turned on, the battery level indicator is switched on and the LED (D or E) corresponding to the position currently held by the rotary dipswitch will turn on. Position 0 (zero) corresponds to the red LED (D), position 1 corresponds to the first yellow LED (row of 7 LED’s (D), and so on. After that, all the LED’s turn on for a few seconds (lamp test) and then ordinary operation is started. The battery level indicator features two voltage thresholds: the stopping threshold and the resetting threshold. The stopping threshold corresponds to the value of the voltage at the end of discharge and depends on the position of the rotary dipswitch (A) located at the back side of the indicator. The resetting threshold corresponds to the reset-point threshold of the device (this value varies along with the discharging current selected by the dipswitch (A) and is close to the battery nominal value). When the voltage value corresponding to the stopping threshold is reached, the last yellow LED will flash for 15 seconds, then the red LED will turn on, and the blocking relay will open. To reset, switch off the battery level indicator, charge the batteries, and then switch on the machine.

BDI OPERATION

When the battery level indicator is switched on, the battery voltage is measured, and:

• If the voltage is below the stopping voltage, the machine will not run.

• If the voltage is higher than the resetting threshold, all the LED’s will turn on again and the battery

level indicator will reset and the machine will run.

• If the voltage ranges b etween the stopping voltage and the resetting voltage, the LED’s will turn on

rapidly according to the condition prior to the switching off. If the previous condition was a stop, the

last yellow LED will flash.

BALANCING INSTRUCTIONS

Page 14 of 30

TO ACHIEVE PROPER MACHINE BALANCE SHIFT SHIMS FROM FRONT TO BACK OR BACK TO FRONT OF BATTERIES

For best operation and maximum battery life, the XTG3 battery burnisher must have the correct pad pressure. The burnisher should require only minor adjustments to the balance. Only the battery shims should be adjusted. The wheel axel positions are factory set and are in the proper locations in the wheel brackets.

Tilt the burnisher back. Remove front cover. Tilt burnisher to upright position.

With a new pad, the burnisher should hesitate and then barely fall back. With a worn pad, the burnisher should barely sit upright.

If burnisher falls back easily, then the batteries need to be moved forward.

Remove several battery spacers from front of batteries

• Slide batteries forward

• Add spacer(s) to rear of batteries

• Slide batteries tight against rear spacers (can be done by tilting machine back quickly)

• Replace remaining spacers in front of batteries (batteries should now be “locked” into position)

•

If burnisher sits upright easily, then the batteries need to be moved back.

Remove some battery spacer(s) from rear of batteries

• Slide batteries back

• Replace remaining spacers in front of batteries (batteries should now be “locked” into position)

•

If batteries are moved as far as possible and proper balance cannot be achieved, then one of the wheels may be moved to achieve balance. The burnisher is factory balanced, so this is usually not necessary unless different batteries are installed by the customer. Most of the time, only one wheel needs to be moved. Any stagger of the wheels should have the left wheel in front (to the front of the machine) of the right wheel.

3. bolt. Leave a little snug to help hold tensioner in place after adjustment. (location shown in fig. 1) Using a 15/16” socket with an extension, fully tighten tensioner from the

4. underside of deck, and back off 10 to 15 degrees. This will be about 2 inches at the end of the socket handle. (Note: This is about one mark on the tensioner. There are five marks on the side of the tensioner, which are difficult to see with the tensioner in place. Each mark is equal to about 15 degrees. This leaves the tensioner at about 60 degrees of tightness.)(see figure 2) While holding position tensioner in this proper location, fully tighten the

5. tensioner bolt from the top. TIGHTEN SECURELY! Make sure tensioner did not slip by pushing or pulling on side of belt away

6. from tensioner. Belt should be tight and move the tensioner arm 10 to 15 degrees (about 1 ").

TROUBLE-SHOOTING

Page 28 of 30

PROBLEM CAUSE POSSIBLE SOLUTION

No sign of power. No on lamp, no BDI readout.

Powers on with key switch, but solenoid does not “click” with rocker switch. Powers on, solenoid “clicks”, but does not run

Pad “bogs down” Too much pad pressure Decrease pressure using directions on Machine will not set upright

with cover on Low runtime (a) Improper charge

Machine vibrates (a) Pad not centered

Noise coming from underside of deck Machine hard to push (a) Worn pad

Machine pulls left (a) Worn pad

Uneven floor buffing (right side of pad polishes and left side does not)

(a) Bad connection (b) Bad connection to BDI (c) On-board charger is

plugged in (d) Batteries dead (e) Charger plugged into

outlet Bad connection Check all connections.

(a) Safety run switch

problem. Not pulling

plunger enough to

activate. (b) Safety run switch wire

connectors may be loose

Too little pad pressure Increase pad pressure using directions on

(b) Old batteries or defective

cell in battery (c) Too much pad pressure. (d) BDI set to too high a

voltage

(b) Pad is torn or worn

excessively Belt is loose and causing belt tensioner to “chatter”.

(b) Worn wheel bearings (c) Pad out of alignment

(b) Wrong pad (c) Right side of pad needs a

little more contact than

the left so “pad assist”

can help pull machine

forward . Right side of pad contacting

too much, therefore left side is not contacting enough.

(a) Check all connections. (b) Make sure connector is fully pushed into

BDI. (c) Disconnect charger from wall outlet. (d) Recharge or replace batteries as needed. (e) Unplug charger from 110v outlet. Charger

has an “inhibit” circuit that prevents machine

from running if charger is plugged in.

(a) Cable may have slipped and sleeve needs

to be re-crimped or replaced. (b) Push in connectors

“Balancing Instructions” page “Balancing Instructions” page

(a) Make sure that batteries get a full charge

after each use. (b) Replace batteries. Best to replace as a set. (c) Balance machine. See “Balancing

Instructions” page. (d) See BDI instruction page on how to set to a

value of 4 for optimal run time and battery

life (a) Remove pad and re-center the pad (b) Replace pad

Tighten belt. See page with “Belt tightening instructions”. (a) Replace pad. (b) Replace bearings or replace wheels. (c) See solution to next problem “Machine pulls

left”. (a) Replace pad (b) Replace pad with pad approved use with XT

burnisher. (c) Add a small shim (.010 thick) between

bearing housing and deck on the right side.

This will “push” right side down toward floor.

(If there are too many shims, then left side

of pad will not contact properly). The reverse of the previous procedure. Remove one of the small shims (.010 thick) between bearing housing and deck on the right side
