check tire wear
Examine tires at least once a week for surface wear and cracks and 
replace them as needed. Replace tires when they become loose on the 
rims or cracks appear.

check handrims
Check handrims at least once a week. Inspect each handrim for rough or 
sharp edges and, if any are found, replace handrims immediately. Ensure 
that all hardware is properly aligned and secure.

check wheel lock engagement
Check wheel lock engagement at least once a week. See Adjust wheel 
locks in Section 5 to adjust wheel lock engagement. If a wheel lock 
is worn or damaged, replace it immediately. Inspect the hardware for 
looseness or signs of wear.
Ensure that the locking mechanism operates smoothly. The locking 
assembly should be tight enough so that the wheel can not rotate or the 
lock slip. Check that the locking shoe does not press against the tire 
when in the unlocked position. Excessive force should not be required to 
either engage or release wheel locks. Oil the wheel lock pivot points with 
one or two drops of 30 weight oil. Remove excess oil and dirt.

check anti-tippers
Check the anti-tippers at least once a week. Ensure that the anti-tippers 
are securely fastened and properly positioned.

check handgrips
Check handgrips at least once a week. Ensure that they are not ripped; 
ensure that they are tight and securely fastened.
