ADJUSTING THE HEAD UNIT

The head unit will should come adjusted from the factory. However, riding on rough terrain and general use may cause the head unit to become loose over time. It may be necessary to adjust the head unit from time to time.

To adjust the head unit:

1.Rotate the handle bar as far right as it will go to expose the HEAD UNIT.

2.The head unit bearings are held in place by two 40mm nuts on the underside. These nuts are separated by a spacer. The top nut provides the adjustment, while the lower nut is a jamb-nut intended to hold the adjustment nut in place.

3.Loosen the lower nut 3-4 turns (fig. 14)

4.Tighten the top adjuster nut to the desired amount, and then re-tighten the lower jamb-nut.

DO NOT over tighten as it will make it difficult to steer and may damage the bearings.

ADJUSTING THE BELTS

The belts will come adjusted from the factory. However, it may be necessary to adjust the pulleys from time to time. The belts must be well aligned onto the pulleys otherwise they may start to rub and chafe, which will result in shortened belt life.

How tight should the belt be?

If the belt is skipping or jumping on the pulley teeth, this is too loose and may be harmful.

If the belt is making a humming sound when the wheel is turning, this is too tight and may cause the belt to snap.

These high-performance tools are engineered to tackle a variety of tough cutting tasks with ease, making them popular choices among users seeking reliability and efficiency.

The dual-line cutting system effectively increases coverage while reducing the time spent on trimming tasks. Moreover, the straight shaft design on both models enhances reach and accessibility, particularly in hard-to-reach areas such as under fences or shrubs.

Durability is a hallmark of the Tanaka brand, and these brushcutters are no exception. Constructed from high-quality materials, both models are resistant to wear and tear, ensuring longevity even in demanding conditions. The TPB-400GX and TPB-350GX also feature an easy-start mechanism, allowing for quick ignition without the frustrating pull starts commonly associated with traditional two-stroke engines.
