HDA SERIES WALK-BEHIND TROWEL • OPERATION MANUAL — REV. #0 (12/1/17) — PAGE 17
Figure 3 shows the location of the trowel's basic
components. Listed below is a brief explanation of each
component.
1.
Gearbox — A helical worm gear drive gearbox
rotates the blades via the engine interface.
ALWAYS
check the gearbox oil level prior to each use. Fill with
Mobil SHC™ 634 or equivalent industrial synthetic
gear oil.
2.
Engine — An air-cooled, 4-stroke, single-cylinder,
OHV, horizontal shaft, gasoline engine. Refer to the
engine owner’s manual for engine operation and
maintenance instructions.
3.
Lifting Bail — Attach the lifting bail to a suitable lifting
device whenever lifting of the trowel is required.
4.
V-Belt Cover — Remove this cover to gain access to
the V-belt.
NEVER operate the trowel with this cover
removed.
5.
Throttle Lever — Controls engine speed. Returns the
engine to
idle when released.
6.
Pitch Control Star Wheel — With the standard
handle installed, rotate the star wheel clockwise
to pitch the blades upwards. Rotate the star wheel
counterclockwise to pitch the blades flat (no pitch).
7.
Handlebar Pad — A foam rubber pad protects the
operator when making contact with the handlebar.
8.
Vibratory Handlebar — T-handle with rubber shock
mounts/isolators to reduce vibration during operation.
9.
Hand Grips (2) — ALWAYS place both hands on the
hand grips when maneuvering the trowel. Replace
the hand grips when they become worn or damaged.
10.
Handlebar Adjuster — Loosen the star wheel to adjust
the height and angle of the handlebar as desired, then
tighten the star wheel firmly to secure the handlebar
in position.
11.
Centrifugal Safety Stop Switch — Stops the engine
and brings the trowel to a halt in the event of a runaway
trowel condition (the operator releases the handle).
12.
Guard Ring — Prevents objects from making contact
with the rotating blades during operation.
NEVER place
hands or feet inside the guard ring while the machine
is running.
13.
Trowel Arms (4) — NEVER operate the trowel with
a bent, broken, or out-of-adjustment trowel arm. If the
blades show uneven wear patterns, or some blades
wear out faster than others, the trowel arms may need
to be adjusted. Refer to the “
Maintenance
” section for
more information.
14.
Blades (4) — Versatile combination blades will satisfy
most troweling needs.
15.
Quick Pitch™ Handle (Optional) — With the
Quick Pitch™ handle installed, pull the T-handle
backwards while squeezing the trigger to pitch the
blades upwards. Push the T-handle forward to pitch
the blades flat (no pitch). Contact MQ unit sales to
purchase this option.
