TROUBLE-SHOOTING

PROBLEM CAUSE POSSIBLE SOLUTION

No sign of power. No on

lamp, no BDI readout.

(a) Bad connection

(b) Bad connection to BDI

(c) On-board charger is

plugged in

(d) Batteries dead

(e) Charger plugged into

outlet

(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.

Powers on with key switch,

but solenoid does not “click”

with rocker switch.

Bad connection Check all connections.

Powers on, solenoid “clicks”,

but does not run

(a) Safety run switch

problem. Not pulling

plunger enough to

activate.

(b) Safety run switch wire

connectors may be loose

(a) Cable may have slipped and sleeve needs

to be re-crimped or replaced.

(b) Push in connectors

Pad “bogs down” Too much pad pressure Decrease pressure using directions on

“Balancing Instructions” page

Machine will not set upright

with cover on

Too little pad pressure Increase pad pressure using directions on

“Balancing Instructions” page

Low runtime (a) Improper charge

(b) Old batteries or defective

cell in battery

(c) Too much pad pressure.

(d) BDI set to too high a

voltage

(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

Machine vibrates (a) Pad not centered

(b) Pad is torn or worn

excessively

(a) Remove pad and re-center the pad

(b) Replace pad

Noise coming from

underside of deck

Belt is loose and causing belt

tensioner to “chatter”.

Tighten belt. See page with “Belt tightening

instructions”.

Machine hard to push (a) Worn pad

(b) Worn wheel bearings

(c) Pad out of alignment

(a) Replace pad.

(b) Replace bearings or replace wheels.

(c) See solution to next problem “Machine pulls

left”.

Machine pulls left (a) Worn pad

(b) Wrong pad

(c) Right side of pad needs a

little more contact than

the left so “pad assist”

can help pull machine

forward .

(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).

Uneven floor buffing (right

side of pad polishes and left

side does not)

Right side of pad contacting

too much, therefore left side

is not contacting enough.

The reverse of the previous procedure. Remove

one of the small shims (.010 thick) between

bearing housing and deck on the right side
