3. STEERING WHEEL TURNS HARD OR VEHICLE TURNS TOO SLOW

Step 1. Check pressure in all tires (should be 45 PSI).

a. If tire pressure is not 45 PSI in all tires, adjust to 45 PSI.

b. If tire pressure is okay in all tires, proceed to step 2.

Step 2.

Check oil level in hydraulic reservoir.

oil level should be between FULL and ADD marks with mast lowered.

a. If oil level is not between FULL and ADD marks on dipstick with mast lowered, add oil (refer to
