During this procedure the bandsaw blade should be tensioned and adjusted. 3. Set the scale so that the scale pointer has the same value and can be read on the scale FIG.
FUEL HANDLING Fuel FIG. 39 Fuel Safety ! WARNING! The fuel used in the one-man sawmill has the following hazardous properties: 1. The fluid, its vapour, and its exhaust fumes are poisonous. 2. Can cause skin irritation. 3. Is highly inflammable. The following are absolutely forbidden when fuelling: • Smoking. • To have flames or hot objects in close proximity. • To have the engine running. Petrol Use leaded or unleaded petrol. The lowest recommended octane grade is 90.
STARTING AND STOPPING ! WARNING! Observe the following before starting the engine: FIG. 40 • The engine must be mounted in the sawmill before starting. Otherwise the clutch can come loose and cause personal injuries. • Keep people and animals well away from the risk zone. Starting a Cold Petrol Engine A cold engine is started as follows: 1. Open the fuel tap (A). 2. Set the stop switch to the start position (B). 3. Activate the choke.
STARTING AND STOPPING Starting the Electric Sawmill ! WARNING! The sawmill must not be started until the appropriate current and voltage has been connected. Use suitable personnel trained in the country in question. FIG. 42 CAUTION! The first time the sawmill is started or when it has been moved to another power outlet: • • Test start the sawmill in accordance with the starting instructions. Check the direction of the bandsaw blade.
USE Securing the Log ! WARNING! Exercise care during all log handling. Heavy lift! Wear boots or shoes fitted with steel toecaps. 1. Fold up the stops (C) on the left-hand side of the rails. 2. Roll the log up against the stops (C). The log must not come closer: • than 300 mm to the end of the rails • than 500 mm to the start of the rails This means that when using two rail sections, the maximum log length is 5200 mm. 3. Raise the log using the height adjuster (B) so that the log’s core is horizontal. 4.
USE Calculating the Yield Measure the log’s top end and determine how the log should be utilised for the timber in question. Include the thickness of the saw cut in the calculation. FIG. 47 The saw cut thickness = 2 mm. Sawing ! WARNING! Use the following protective equipment when sawing: FIG. 48 • Boots or shoes fitted with steel toecaps. • Hearing protection. • Eye protection. • Always have a first aid kit nearby. Before starting the engine, check that: • All guards are fitted and undamaged.
USE ! ! WARNING! Check during sawing that the bandsaw blade does not hit the folding stops or log lock. WARNING! The saw carriage must not be moved backwards while the bandsaw blade is in motion. Otherwise the bandsaw can jump off and cause personal injury. Starting the Petrol Engine 1. Start the engine. See page 24. Starting the Electric Motor 1. Start the electric motor. See page 25. Sawing FIG. 49 2. Move the saw carriage forwards and cut off the sapwood. 3. Remove the sapwood. 4.
USE 8. Loosen the log and turn it 90°. FIG. 51 9. Adjust the top end of the log using the height adjuster and secure the log with the flat surface tightened against the stop. 10. Cut off the upper sapwood. 11. Loosen the log, turn it 180°, lower the height adjuster, and secure the log. FIG. 52 12. Cut the block according to the previous instructions. Remember to compensate for the thickness of the bandsaw blade for each adjustment of the bandsaw blade’s height.
MAINTENANCE Bandsaw Blade ! WARNING! The bandsaw blade is sharp and can cause cuts. Warning for personal injury. Wear protective gloves whenever you handle the bandsaw blade. The bandsaw blade should be set and sharpened regularly to give optimal performance. During normal sawing of most species of wood this should be done at intervals of approx. 2 hours of effective cutting time. Effective cutting time refers to only the time that the bandsaw blade actually works.
MAINTENANCE Saw Setting Pliers FIG. 56 For optimal results the bandsaw blade should be set using the saw setting pliers as described on page 30. The saw setting pliers are adjusted to the correct setting size. Place the saw setting pliers over the saw tooth so that the pliers’ fixing angles rest on the two closest teeth. Activate the pliers and the saw tooth will be set away from the operator.
MAINTENANCE Sharpening ! FIG. 57 WARNING! The bandsaw blade is sharp and can cause cuts. Warning for personal injury. Wear protective gloves whenever you handle the bandsaw blade. After sharpening, the bandsaw blade should be set as described in the instructions on the previous page. FIG. 58 The more accurate the sharpening, the straighter and smoother the bandsaw blade runs when cutting the log. Radii The radius in the area (A) should be 1-3 mm. A radius under 1 mm increases the risk of cracking.
MAINTENANCE Band Wheel Adjustment After the one-man saw has been used for a long period, the band wheel bearings will start to wear and change position. Meanwhile, the foundation’s working geometry will have stabilised. This means the parallelism of the band wheels may need to be adjusted. FIG. 61 Adjustment is performed as follows: 1. Ensure that the electric power has been disconnected. Unplug the electrical contact or short-circuit the petrol engine. 2.
MAINTENANCE Checking the Braking Function FIG. 64 For the one-man saw to meet safety requirements, the braking function must be checked at least once per week. Check the braking function in the following way: 1. Start the sawmill motor/engine. 2. Start the bandsaw blade with the control unit (4). 3. Release the control unit and the bandsaw should stop within 5 seconds. 4.
