SAFETY INSTRUCTIONS

The Bullfloat models HAL 150/300 have been developed and
tested in accordance with strict International Safety Standards.

This section contains general advice.
Regular maintenance of the Bullfloat promotes safe

operation.

■

When in doubt and/or when you are operating the Bullfloat
for the first time, always read the necessary instructions in
this manual.

■

Wear safety shoes with extra protection (steel caps and
anti-slip soles).

■

Place the wires between the electrical source and the work
area in such a way that they can not be damaged or your
co-workers cannot trip over them.

■

Do not leave any tools or parts laying around on the work
floor, as this can cause accidents.

■

Watch where you are going; the ground can be slippery.

■

Take care that you do not injure yourself on objects, such
as scaffolding and reinforcement materials, which can be
found directly or indirectly in the working area.

■

Pay attention to your own safety and that of your fellow
workers.

■

Be careful when lifting and carrying the Bullfloat. Do not
bend forwards when picking up the apparatus, but bend
your knees. Ensure that the working area is within your
reach, so that you do not have to bend forward.

The following safety-aspects specifically apply to those
Whiteman products which are equipped with a
gas-engine.

■

Wear working-gloves, safety glasses and protective
clothing during refueling.

■

Make sure that there is sufficient ventilation during refueling.

■

Refuel only after the engine has cooled off sufficiently.

■

It is strictly forbidden to refuel:

• in the direct vicinity of a open fire or other flammable
materials,

• in explosion endangered places.

■

Do not use the Bullfloat with a
gas-engine
places, such as pits etc.

■

ventilation in spaces which are surrounded
by walls. Never inhale exhaust gases, they
can damage your health and that of your
fellow workers.

Refueling of fuel, while the engine is hot,
might lead to a very dangerous situation
including an explosion and fire.

indoors or in poorly ventilated

Make sure that there is sufficient

■

Ensure that you are qualified (familiar with the contents of
this manual) to operate and carry out light maintenance
work to the Bullfloat.

■

Check that the electrical source complies with the local
regulations.

■

Use grounded extension cords, when it is necessary to
use extension cords.

■

Use an electrical source which is provided with a ground
leakage switch between the electrical mains and the
Bullfloat.

■

Ensure that the wall socket and possible connections
between the extension cords are protected against
dampness.

■

Do not pull the plug out of the wall socket or extension
cords by it’s cord, use the plug.

■

To avoid getting an electric shock, do not
touch the high-tension cable or spark plug
cap while the engine is running.

General Safety Instructions

■

When operating the Bullfloat wear ear protection, safety
glasses, a safety helmet, gloves which do not conduct
electricity and protective clothing.

■

Ensure that all symbols on the Bullfloat — can always be
clearly read.

■

Regularly check the Bullfloat’s connections.

■

When cleaning the Bullfloat, ensure that no water or
cleaning detergents, under high pressure, get into the
motor housing or plug connections.

■

When the Bullfloat is not being used for long periods of
time, then it must be store in a dry and clean area.

Bullfloat HAL 150 & 300 — PARTS & OPERATION MANUAL — REV. #1 (05/27/99) — PAGE 7

Important Safety Checks for the electrical Bullfloat

■

Check the feeder cable and extension cords outer casing
before you connect the Bullfloat to the electrical mains.

■

Check the feeder cable’s attachment on
the bullfloat, before you connect the Bullfloat
to the electrical mains. The cable must be
correctly attached to the Bullfloat.

■

Ensure that the feeder cable does not

graze past any sharp objects.

■

The use of extension cords are permitted, if they are
completely watertight.

■

Switch the Bullfloat “off” when the electrical
power cuts off.This prevents the Bullfloat from
starting suddenly when the electrical power
comes on again.

■

Check the feeder cable and extension cord’s attachments
regularly. When the Bullfloat is in operation, the plugs can
loosen due to the vibrations.

SAFETY INSTRUCTIONS

■

Connect the Bullfloat to an alternating voltage source of
115VAC, which is provided with a ground switch, with a
frequency of 60 Hz.

■

Check that the ventilation openings in the motor housing
are free from dirt and moisture.

■

Regularly check the connections of the feeder cable to
the switch.

Explanation of the utilized safety symbols.

■

Disconnect the electrical supply to the Bullfloat, before you
start to clean or service the Bullfloat.

1. Safety glasses, safety helmet and ear protection
compulsory.

2. Gloves compulsory.

3. Safety shoes with extra protection compulsory.

4. Dangerous electrical voltage.

5. Before opening the motor housing remove the plug.

6. Inflammable material.

7. Pls. read the operation-instructions

8. Careful, danger!

Tip: Ask the manufacturer for clarification, if you have any

questions about any of these safety instructions.

HAL 150 AND 300 — WHAT IS A BULLFLOAT

What is a Bullfloat?

A Bullfloat is an apparatus with a vibrating alloy blade that
smooths and compacts the top layer of freshly poured
concrete, without the need for guiding rails.

Before the Bullfloat is brought into action, the concrete should
be distributed and compacted by means of a vibrator.

The vibrator is used in combination with a laser, in order to
adjust and control the height of the concrete floor.

The Bullfloat consists of an operating handle, an electrical or
gas-engine vibrating-unit and an aluminium blade, available
in 5 lengths: 1m, 1.5m, 2m, 2.5m, and 3m.

The switch is located on the operating handle with which the
electrical vibrating-unit is switched ‘ON’ and ‘OFF’. The gas-
engine vibrating-unit is operated by means of a gas throttle
also located on the operating handle.

Operation

The drive-unit of the Bullfloat is started by turning the knob of
the electric-speed-regulator to the ‘ON’ position (electrical), or
by pulling the recoil-starter of the gas-engine.

An excentric part is set in motion by the drive-shaft of the motor.
This rotating motion sets the aluminium blade in vibration. The
vibrating motion of the blade smooths and compacts the
surface of the concrete.

HAL 150 AND 300 — OPERATION

This section describes the operation of the HAL 150 &
300 Bullfloats.

Tip: For the location and description of the Bullfloat’s parts,

which are mentioned in the text, refer to the illustration figure
(page. 9): What is a Bullfloat.

How to assemble the HAL 150 & 300 Bullfloats.

When delivered the Bullfloat is not ready for use.You only have
to carry out the following procedures to assemble them:

1. Connect the switch (an electronic speed regulator, or a
gas throttle), to the operating handle by means of the
bracket and the butterfly nut. Now lock the bracket by
tightning the butterfly nut. (Fig. No. 2.0)

2. Stick the operating handle into the shaft of the motor unit
frame.Make sure that the operating handle is locked
properly.

Operation and use of the Bullfloat

This section describes how to operate and use the Bullfloat.In
the text are numbers in brackets. These numbers are position
numbers and they correspond to the numbers in the parts list
of the corresponding figures.

Careful: Read the safety instructions before you switch
on the apparatus.

Careful: Prevent the Bullfloat, from sinking into the concrete.

After the motor has been switched on, immediately move the
Bullfloat backwards.

Tip: Before the Bullfloat is brought into action, first compact
the freshly poured concrete floor with a poker-vibrator while at
the same time adjust the height of the floor by means of a
laser device.

Tip: Pour concrete lanes of approx. 3 ft. wide and approx. 15
ft. long. You can finish this surface in one pass without any
problem.

Figure 2.1

Adjusting the blade-pitch

Use position (I), when smoothing freshly poured concrete.

(Fig. No. 2.1)
Use position (II), in the event you want to smooth the same

lane once again.(Fig. No. 2.1)

Tip: When using a low slump concrete, move the Bullfloat
slowly across the surface of the concrete. When using a high
slump concrete, move the Bullfloat faster across the surface
of the concrete.
