WC-42S CONCRETE MIXER — PRE-INSPECTION (GAS ENGINE)

Before Starting

1.Read safety instructions at the beginning of manual.

2.Clean the mixer, removing dirt and dust, particularly the engine cooling air inlet, carburetor and air cleaner.

3.Check the air filter for dirt and dust. If air filter is dirty, replace air filter with a new one as required.

4.Check carburetor for external dirt and dust. Clean with dry compressed air.

5.Check fastening nuts and bolts for tightness.

Engine Oil Check

1.To check the engine oil level, place the mixer on secure level ground with the engine stopped.

2.Remove the filler dipstick from the engine oil filler hole (Figure 7) and wipe it clean.

Figure 7. Engine Oil Dipstick (Removal)

3.Insert and remove the dipstick without screwing it into the filler neck. Check the oil level shown on the dipstick.

4.If the engine oil level is low (Figure 8), fill to the edge of the oil filler hole with the recommended oil type (Table 6). See Table 2 for the oil capacity of your type engine.

Explosive Fuel

Fuel Check

If your mixer has a gasoline engine, determine if the engine fuel is low. If fuel is low, remove the fuel filler cap and fill with unleaded gasoline. Motor fuels are highly flammable and can be dangerous if mishandled. DO NOT smoke while refueling. DO NOT attempt to refuel the trowel if the engine is hot! or running.

1.Remove the gasoline cap located on top of fuel tank.

2.Visuallyinspecttoseeiffuellevelislow. Iffuelislow,replenish with unleaded fuel.

3.When refueling, be sure to use a strainer for filtration. DO NOT top-off fuel. Wipe up any spilled fuel.

V-belt Check

A worn or damaged V-belt can adversely affect the performance of the mixer. If a V-belt is defective or worn simply replace the V- belt as outlined in the maintenance section of this manual.

Blade Check

Check for worn blades. If using a steel tub and the blades are worn, replace the entire tub assembly. Remember the blades are welded to tub.

If using a plastic tub, replace the blades using the part numbers referenced in the parts section of this manual.

Start/Stop Switches

This mixer has been equipped with a start/stop switches for both the gasoline and electric motor mixers.These switches should be tested every time the engine or motor is started.

Grease Fittings (Zerk)

Check the zerk grease fittings (Figure 27) as shown in the maintenance section of this manual.These grease fittings lubricate the handwheel and the yoke mechanism.
