When there is no water in the washing tank, do not work, otherwise, it will damage the electric
motor.
(15) Air Filter
If the air filter is clogged by the dusts, it will increase the inhalation resistance, so the motor power
will be decreased and the oil wear will be increased. You must clean and change the filter element.
Cleaning method: lift down the lid of the air filter and take out the filter element and use the
compressed air to blow away the dusts above the filter element.
(16) Brake Fluid
The fluid level should be between the highest and the lowest fluid level. You should add the same
brake liquid when the fluid level is low.
Warning
If the liquid level of the brake fluid reservoir is too low, the light on the
instrument desk will be lighted to prompt filling-up.
