HHN-34TVD • RIDE-ON POWER TROWEL — OPERATION MANUAL — REV. #1 (05/08/06) — PAGE 24

HHN 34TVD — INITIAL START-UP

This section is intended to assist the operator with the initial
start-up of the HHN 34TVD trowel. It is extremely important that
this section be read carefully before attempting to use the trowel
in the field.

DO NOT use your trowel until this section is thoroughly
understood.

1.

Check the gearbox oil level in both gearboxes
by viewing the sight glass at the rear of the
gearbox. See Figure 8.

Fuel

Determine if the engine fuel is low (Figure 9). If fuel level is low,
remove the fuel filler cap and fill with appropriate engine fuel.
The HHN34TVD uses diesel fuel.

2.

The oil level of the gear box should be at the half-way point
of the sight glass (Figure 8). The gear box oil capacity is 1
U.S. Gallon, (3.79 liters). If additional oil is required, unscrew
the oil fill plug located on top of the gearbox, and refill with
ISO 220 A GMA GR 5 EP oil.

Figure 8. Gearbox Oil Plugs/Sight Glass

Figure 9. Fuel Gauge

Figure 7. Engine Oil Dipstick

1.

Pull the engine oil dipstick from its holder.

2.

Determine if engine oil is low (Figure 7), add
correct amount of engine oil to bring oil level
to a normal safe level. (See Recommended
Viscosity Grades, Table 4, Page 29).

Gearbox Oil Level

Handle fuel safely. Motor fuels are highly flammable and
can be dangerous if mishandled. DO NOT smoke while
refueling. DO NOT attempt to refuel the ride-on trowel if the
engine is hot or running.

Engine Oil Level

See Figures 3 and 4 (Pages 20 and 21) for the location of
any control or indicator referenced in this manual.

Failure to understand the operation of the HHN 34TVD Trowel
could result in severe damage to the trowels or personal
injury.
