-- in areas with possible falling objects
unless equipped with overhead guard.
2. Before starting machine:
-- check for fuel, oil, and liquid leaks.
-- keep sparks and open flame away from
refueling area.
-- make sure all safety devices are in
place and operate properly.
-- check brakes and steering for proper
operation.
3. When starting machine:
-- keep foot on brake and directional
pedal in neutral.
4. When using machine:
-- use brakes to stop machine.
-- go slow on inclines and slippery
surfaces.
-- use care when reversing machine.
-- move machine with care when hopper
is raised.
-- make sure adequate clearance is
available before raising hopper.
-- do not carry passengers on machine.
-- always follow safety and traffic rules.
-- report machine damage or faulty
operation immediately.
5. Before leaving or servicing machine:
-- stop on level surface.
-- set parking brake.
-- turn off machine and remove key.
6. When servicing machine:
-- avoid moving parts. do not wear loose
jackets, shirts, or sleeves.
-- block machine tires before jacking
machine up.
-- jack machine up at designated
locations only. Block machine up with
jack stands.
-- use hoist or jack that will support the
weight of the machine.
-- wear eye and ear protection when
using pressurized air or water.
-- disconnect battery connections before
working on machine.
-- avoid contact with battery acid.
-- avoid contact with hot engine coolant.
-- allow engine to cool.
-- keep flames and sparks away from fuel
system service area. Keep area well
ventilated.
-- use cardboard to locate leaking
hydraulic fluid under pressure.
-- use tennant supplied or approved
replacement parts.
7. When loading/unloading machine
onto/off truck or trailer:
-- Turn off machine.
-- Use truck or trailer that will support the
weight of the machine.
-- Use winch. Do not drive the machine
onto/off the truck or trailer unless the
load height is 380 mm (15 in) or less
from the ground.
-- Set parking brake after machine is
loaded.
-- Block machine tires.
-- Tie machine down t truck or trailer.
WARNING: Engine emits toxic gases.
Severe respiratory damage or
asphyxiation can result. Provide
adequate ventilation. Consult with your
regulatory authorities for exposure
limits. Keep engine properly tuned.
WARNING: Raised hopper may fall.
Engage hopper support bar.
WARNING: Lift arm pinch point. Stay
clear of hopper lift arms.
WARNING: Moving belt and fan. Keep
away.

PUSHING, TOWING, AND TRANSPORTING
THE MACHINE
PUSHING OR TOWING THE MACHINE
If the machine becomes disabled, it can be
pushed from the front or rear, but towed only from
the rear.
The propelling pump has a bypass valve to
prevent damage to the hydraulic system when the
machine is being pushed or towed. This valve
allows a disabled machine to be moved for a very
short distance and at a speed to not exceed 1.6
kp/h (1 mph). The machine is NOT intended to be
pushed or towed a long distance or at a high
speed.
ATTENTION! Do not push or tow
machine for a long distance and without
using the bypass valve, or the machine
hydraulic system may be damaged.
Turn the bypass valve 90_from the normal
position before pushing or towing the machine.
The illustration shows the bypass valve in the
pushing or towing position.

TRANSPORTING THE MACHINE
1. Position the rear of the machine at the
loading edge of the truck or trailer.
FOR SAFETY: Use truck or trailer that
will support the weight of the machine.
NOTE: Empty the hopper before transporting the
machine.
2. If the loading surface is not horizontal or is
higher than 380 mm (15 in) from the ground,
use a winch to load machine.
If the loading surface is horizontal AND is
380 mm (15 in) or less from the ground, the
machine may be driven onto the truck or
trailer.
3. To winch the machine onto the truck or
trailer, attach the winching chains to the rear
tie down locations.
The rear tie-down locations are through the
U--bolt section of the main frame under the
side bumpers toward the rear.

GENERAL INFORMATION
1--7
800/810 MM337 (6--01)
4. Turn the bypass valve 90_from the normal
position before winching the machine onto
the truck or trailer. See PUSHING OR
TOWING THE MACHINE section of this
manual. Make sure the machine is centered.
FOR SAFETY: When loading machine
onto truck or trailer, use winch. Do not
drive the machine onto the truck or
trailer unless the loading surface is
horizontal AND is 380 mm (15 in) or less
from the ground.
5. Position the machine onto the truck or trailer
as far as possible. If the machine starts to
veer off the centerline of the truck or trailer,
stop and turn the steering wheel to center
the machine.
6. Set the parking brake and block the machine
tires. Tie down the machine to the truck or
trailer before transporting.
The two front tie--down locations are through
the U--bolt section of the main frame in front
of the wheels.
The two rear tie--down locations are through
the U--bolt section of the main frame under
the side bumpers toward the rear.
7. If the loading surface is not horizontal or is
higher than 380 mm (15 in) from the ground,
use a winch to unload machine.
If the loading surface is horizontal AND is
380 mm (15 in) or less from the ground, the
machine may be driven off the truck or
trailer.
FOR SAFETY: When unloading machine
off truck or trailer, use winch. Do not
drive the machine off the truck or trailer
unless the loading surface is horizontal
AND 380 mm (15 in) or less from the
ground.

MACHINE JACKING
Empty the hopper before jacking the machine.You
canjackupthemachineforserviceatthe
designated locations. Use a jack or hoist that will
support the wieght of the machine. Always stop
the machine on a flat, level surface and block the
tires before jacking the machine up.
The front jacking locations are the flat bottom
edge of the machine frame next to the front tires.
The rear jacking location is the middle of the rear
bumper.
FOR SAFETY: When Servicing Machine, Block
Machine Tires Before Jacking Machine Up.
FOR SAFETY: When Servicing Machine, Jack
Machine Up At Designated Locations Only.
Block Machine Up With Jack Stands.
STORING MACHINE
Before storing the machine for an extended period
of time, the machine needs to be prepped to
lessen the chance of rust, sludge, and other
undesirable deposits from forming. Contact
TENNANT service personnel.

HARDWARE INFORMATION
The following charts state standard plated
hardware tightening ranges for normal assembly
applications. Decrease the specified torque by
20% when using a thread lubricant. Do not
substitute lower grade hardware for higher grade
hardware. If higher grade hardware than specified
is substituted, tighten only to the specified
hardware torque value to avoid damaging the
threads of the part being threaded into, as when
threading into speed nuts or weldments.
