Clean any dirt, ice, or other foreign material from the extinguisher and bracket

Remove the extinguisher from the bracket and clean the extinguisher surface where the bracket pads contact it

Examine the bracket pads which hold the extinguisher in place. Clean the pad surfaces to maintain their gripping power on the extinguisher. Check the pads for resiliency, and replace if necessary

Inspect the bracket. If it has been bent, replace it. If it has been cracked, repair or replace it

If any welding is performed, take steps to protect the bracket pads from excessive heat

Grease each moving part of the bracket arm and test its action. The bracket must be able to hold the extinguisher firmly, but release easily when necessary

Check to see that the bracket is firmly mounted. Tighten or replace mounting fasteners, or re-weld connections as needed

Avoid possible rust damage by cleaning and painting wherever bare steel is exposed

Following extinguisher maintenance, secure the extinguisher in its bracket. If the bracket does not hold the extinguisher securely or the bracket is difficult to close, replace the affected part and/or bracket

Before proceeding to recharge any extinguisher, visually examine the unit for any physical damage or impairment which may further dictate the need for maintenance.
