OR DRIVE SHAFT REPLACEMENT:
A. Adjust the handle to enable the buffer to stand on
rear wheels.
•
Handle must be in shipping (forward) position to
insure stability in the “tilt back” position. A
second person should aide in the lift and to
secure the buffer while being serviced.
•
Do not use “T” handle when attempting to tilt
back machine for service or cleaning. “T” handle
is designed for control during operation — Do not
use excessive vertical pressure.

E. Remove belt(s). (Replace if worn.)
F. To remove driveshaft unit: Remove retaining bolt &
clip—pull driveshaft out of housing—use of a slide
hammer may assist in removal (Do not pry with
crow bar). While drive shaft is removed, spin
bearings. If roughness is felt, bearing replacement
may be necessary.

NOT ALL OF THESE STEPS WILL BE NECESSARY FOR
ALL JOBS, BUT IF THEY ARE, THE ENTIRE JOB CAN
BE COMPLETED WITH A FEW TOOLS IN LESS THAN
15 MINUTES!!!
IV. LUBRICATION INSTRUCTIONS:
A. Refer to engine manufacturer’s owners manual and
comply completely with the lubrication instructions.
Any evidence of under
- lubrication will make a
claim against the manufacturer invalid.
B. Keep a good service log on each machine with the
date, hour meter reading, type(s) of service performed
and the name of the person who performed them.
This will assist you and Aztec in spotting weaknesses
in our respective areas of responsibility. A standard
maintenance log is available at any stationary store.
V. TROUBLESHOOTING
THE ELECTRICAL SYSTEM
A. First, check all wire connections for obvious problems.
Remove LPG tank, then remove battery box cover. Check
all connections visibly and physically. If any “loose”,
damaged or unconnected wires are noticed, contact Aztec
and/or put wires back in their proper place.
•
Always wear a face shield, safety glasses and
protective clothing when working around a battery!!
The gases can be explosive and the acid is highly
corrosive to metals, cloth and ALL HUMAN
TISSUE (skin, eyes, etc.) If the battery post(s) are
corroded, remove the wires and clean posts and
wires well. You may wish to put some axle grease
on the posts or the battery after they are cleaned.
This will slow down the battery corrosion process.
IF NOTHING OBVIOUS IS NOTED, A MORE DETAILED
INVESTIGATION IS WARRANTED. BEFORE ANY SUCH
TROUBLE SHOOTING BEGINS, THE FOLLOWING
THINGS SHOULD BE DONE:
