Husqvarna SMB 70, SMB 70 E Handlebars FIG, Cleaning Tank FIG, Band Wheels FIG, Electric Motor FIG

DESCRIPTION

Handlebars (FIG. 5)

The saw carriage is operated and moved for- ward with a vibration-free steering handlebar (5), located on the carriage’s right hand side. The handlebar is equipped with start and stop controls (4) for the bandsaw.

Cleaning Tank (FIG. 5)

The saw carriage is equipped with a cleaning tank (3). The tank is located beside the handle- bars. Cleaning fluid is applied to the blade by opening the tank valve.

Band Wheels (FIG 6)

The bandsaw blade runs over two band wheels (26), which are made of cast aluminium and are balanced to provide smooth operation. The band wheels are equipped with bearings, and are adjustable, partly to tension the bandsaw blade and partly to adjust the correct alignment of the bandsaw blade.

The band wheels are fitted with scrapers so that sawdust and the like does not penetrate between the bandsaw blade and the band wheel.

One of the band wheels is powered by the engine/motor via an adjustable belt.

Bandsaw and Band Guide (FIG 6)

Two band guides (8) are used to keep the bandsaw blade (9) in the correct position during cutting. One of the band guides is placed in front of the powered band wheel and ensures correct entry onto the wheel. The other band guide is adjustable and is positioned above the bandsaw blade before it runs onto the log. This band guide absorbs the forces from the log and prevents the bandsaw blade from shifting.

Propulsion

Petrol Engine (FIG. 7)

The one-man saw is run with an air-cooled four- stroke engine (15). A clutch is located on the engine’s drive axle that starts, stops, and brakes the bandsaw blade. The speed of the engine is regulated with the operating control on the handlebars. See the enclosed manual for a description of the engine.

Electric Motor (FIG. 8)

The one-man saw is powered by a 3-phase motor (37). The motor is started and stopped with the start and stop buttons on the distribution box, which has built-in motor protection. There is also a connection for an electric cable with single polarity reversal (FIG. 8A), and a main switch (FIG. 8B.). A clutch is located on the motor’s axle and starts, stops, and brakes the bandsaw blade.
