BLADES General ! CAUTION! Inspect the blade for damage, cracks, loss of segments, warping, overheating, excessive wear or a damaged tri-arbor hole. If the blade shows any of these problems, discard the blade. Make sure the blade is marked with a maximum operating speed greater than 4450 rpm. Use only 6QOCJCYM 2QYGT Excel Series blades or blades marked with a maximum operating speed greater than 4450 rpm.
ASSEMBLING AND ADJUSTMENTS General ! • Remove the blade block guard. • Insert one the two wrenches supplied, in the slot at the front of the engine and one on the blade shaft bolt. • Rotate the blade shaft counter-clockwise with wrench on the blade shaft bolt until the second wrench engages the flats on the other end of the shaft. • Remove the blade shaft bolt by continuing to turn the bolt counter-clockwise. • Remove the outer blade flange. • Discard the old skid plate.
ASSEMBLING AND ADJUSTMENTS • • Mount the outer blade flange. Tighten the bolt firmly. Install a new skid plate. Hook the front of the skid plate on the front blade block shaft pin. Connect the rear blade block shaft and the rear of the skid plate by installing the locking pin. • Mount the blade block guard. Tighten until fully seated against the blade block. • Lift the front and rear of the skid plate to ensure the blade slides freely through the skid plate.
FUEL HANDLING General ! WARNING! Running an engine in a confined or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. Use fans to ensure proper air circulation when working in trenches or ditches deeper than one meter. Fuel and fuel fumes are highly flammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.
OPERATING Protective equipment General safety precautions General • ! Do not use the machine unless you are able to call for help in the event of an accident. Personal protective equipment You must use approved personal protective equipment whenever you use the machine.

Use and care • Experience is very important when running the machine. A skilled worker is highly recommended.
OPERATING • Base friction. • Slab restraints. • Layout of foundations, racks, pits, equipment pad, trenches, etc. • Environmental factors - temperature, wind, humidity. • Methods and quality of concrete curing. Generally, contraction joint patterns should divide slabs into approximate square panels per the recommended spacing shown. Recommended contraction joint spacing Concrete thickness, mm (in.) Maximum spacing, m (ft.) 90 (3.5) 2,4 (8) 100, 114 (4, 4.5) 3,0 (10) 125, 140 (5, 5.
