Trowelling Machine

Safety

Hazards and Risks

•

Never allow an untrained person to operate machine without adequate instruction.

•

Ensure all users read, understand and follow the operating instructions.

•

Serious injury may result from improper or careless use of this machine.

•

Power trowels are heavy units and require a multiple person lift, using correct lifting techniques and people

of appropriate strength. Where provided, use the lifting eye for mechanical lifts using approved lifting

devices.

Mechanical Hazards

•

DO NOT operate the machine unless all protective guards are in place.

•

Ensure that the motor operation switch is in the OFF position and the spark plug ignition lead is

disconnected before removing the guards or making adjustments.

•

DO NOT increase the governed no-load motor speed above 3,500RPM. Any increase may result in personal

injury and damage to the machine.

•

Be sure the runaway protection switch provided is working properly so that if the handle should slip away

from your control, the ignition supply will be cut off. However momentum may allow the handle to rotate one

full turn before stopping the machine. Step away from the machine if control is lost.

•

Take care not to come in contact with the muffler when the engine is hot, since it may result in severe burns.

•

Keep hands and feet clear of rotating or moving parts as they will cause injury if contact is made.

•

It is important that the operator retains a firm grip with the left hand at some point on the handle when

starting the engine, preferably close to throttle control.

•

When starting the trowel do not exceed ¼ throttle setting. A higher setting could engage the centrifugal

clutch causing the handle to rotate.

•

Be careful with the trowel around pipes sticking out of the floor or other obstacles. Should the trowel blades

catch on these, serious damage to the machine or harm to the operator may result.

•

Ensure that repairs to the motor and machine are carried out by qualified personnel.

Fire & Explosion Hazards

•

PETROL is extremely flammable and explosive under some conditions.

•

ENSURE that petrol is only stored in an approved storage container.

•

DO NOT refuel the motor while it is in operation or hot.

•

DO NOT refuel the motor in the vicinity of sparks, naked flames or a person smoking.

•

DO NOT overfill the fuel tank and avoid spilling petrol when refuelling. Spilled petrol or petrol vapour may

ignite. If spillage occurs, ensure that the machine is dry before starting the motor.

•

Ensure that the fuel tank cap is securely fitted after refuelling.

Chemical Hazards

•

DO NOT operate or refuel a petrol motor in a confined space without adequate ventilation.

•

Carbon monoxide exhaust gases from internal combustion motor driven units can cause death in confined

spaces.

•

Exercise caution and ensure that the perimeter of elevated formwork or platforms is protected.

•

Always maintain good footing so that you do not slip and lose control of the handle when starting or

operating the trowel.

•

Always ensure that the operators have been properly trained prior to using the equipment.

•

Children and small animals should NEVER be present in the work area during operation of the trowelling

machine.

•

ALWAYS check your trowelling machine for loose or missing nuts and bolts before starting. Tighten any

loose fasteners and replace missing or broken parts.

•

Perform all routine maintenance as described within this manual. Failure to do so will void your warranty and

will eventually result in premature equipment failure.

•

NEVER perform maintenance on a running piece of equipment. Shut down the engine and allow it to cool

before servicing the trowelling machine, including mechanical work or lubrication.

•

ALWAYS replace missing, damaged or unclear safety labels to ensure operator awareness and safety.

•

NEVER operate the trowelling machine with missing or damaged safety guards. Replace immediately with

appropriate Nexus parts.

•

NEVER put hands, feet, or other appendages inside the guard ring or belt guard while the engine is running,

even at idle or with protective clothing, as serious injury may result.

•

NEVER wear loose fitting clothing or jewellery around rotating equipment such as the trowelling machine as

it may become entangled in the machinery, resulting in serious injury.

•

NEVER fuel the trowelling machine while the engine is running. Ensure the engine has cooled sufficiently

before refuelling to avoid igniting gasoline fumes.

•

ALWAYS refuel the trowelling machine in a well-ventilated area, away from ignition sources such as sparks,

flames, and lit cigarettes. Smoking while fuelling the equipment may result in explosion.

•

NEVER operate the trowelling machine in explosive environments such as those where paint fumes,

methane, natural gas, fine particulate, aerosol propellant, or solvent fumes are present.

•

NEVER smoke near the trowelling machine as stray gasoline fumes may ignite. Operating the trowelling

machine around an open flame may also result in explosion.

•

ALWAYS shut down the engine and allow it to cool off before lifting or transporting the trowelling machine.

Operation

Technique

The easiest direction to pull the trowelling machine is backward. Pulling gently on the handle while holding it with

both hands will cause it to float toward you.

The handle will try to rotate away from you while the engine is running, so hold it firmly to

keep it steady.

If the entire trowel is pulling to the right or left, balance it by lifting up or pressing down on the handle. Do not try

to stop the sideways motion of the trowel with direct sideways force, balance it by lifting or pressing down on the

handle. Practice holding the trowel steady in one place for a few minutes at a time.

To move sideways it is always best to let the trowel do the work. The rotating blades create a sideways force

when the trowel is leaned forward or backward. Lift up on the handle to make the machine go left, or press

downward on the handle to make the trowel go to the right. The best way to remember this is “Lift to go Left”.

Never press or lift with enough force to make the blades edges dig into the concrete.

Trowelling

Trowelling the concrete surface eliminates large aggregates near the surface, levels bumps and depressions,

and consolidates the surface to make it stronger. The surface must first be sufficiently cured to support the

weight of the trowel. The surface should first be levelled using a float or vibratory screed. To use the standard

finish blades, the concrete should be cured enough that the operator does not leave a footprint deeper than

about 3mm (1/8 inch).

The ideal way to trowel is to work backward, traveling up and down the slab pulling the trowelling machine

towards you and making elongated, overlapping sweeps (see image below).

Ideal trowelling motion

This allows you to thoroughly cover your footprints in the concrete as you walk. Work steadily and patiently,

going too fast will result in poor consolidation and an unattractive finish. Each pass should be made in a

perpendicular direction to the previous one (see image on the next page).

Trowelling Machine

Trowelling pass direction

ALWAYS look where you are going. Be aware of any pipes or other protrusions from the

concrete to avoid tripping or striking the blades. Striking the blades can bend the trowel

arms or damage the drivetrain.

Maintenance

Spark Plug

Clean or replace the spark plug as needed to ensure proper operation.

Refer to the table below for frequency.

The spark plug becomes very hot during operation and remains hot for a while after stopping

the engine. Do not touch the spark plug while it is hot.

Note: Refer to the Technical Data for the recommended spark plug type and the electrode

gap setting.

•

Remove the spark plug and inspect it.

•

Replace the spark plug if the insulator is cracked or chipped.

•

Clean the spark plug electrodes with a wire brush.

•

Set the electrode gap (a) 0.6 – 0.7 mm

•

Tighten the spark plug securely.

Air Filter

NOTE: NEVER run the engine without the air cleaner. Severe engine

damage will occur.

The engine is equipped with a dual-element air cleaner.

Under normal operating conditions, the elements should be cleaned once

every week. Under severe, dry and dusty conditions, the elements should

be maintained daily. Replace an element when it is saturated with dirt that

cannot be removed.

•

Remove the air cleaner cover (a). Remove the filter assembly by pulling

it straight up. Inspect both elements for holes or tears. Replace

damaged elements.

•

Wash the foam element (b) in a solution of mild detergent and warm

water. Rinse it thoroughly in clean water. Allow the element to dry

thoroughly.

•

Tap the paper element (c) lightly to remove excess dirt or blow

compressed air through the filter from the inside out. Replace the paper

element if it appears heavily soiled.

Oil

Please check oil before every use. To drain the oil, remove the drain plug with a 10mm socket.

Be careful! Ensure there is a proper draining bowl for the old oil. Trowelling machine may need to be

slightly tilted.

Once drained, fasten the screw plug back in. Refill with 600ml of 10W30 (recommended) engine oil by removing

the dipstick (circled in red) and pouring into cavity.
