Inspect Air Filter and Replace Filter if Damaged
Do Not Use the Machine with a Dirty, Damaged, or Missing Air Filter
Reinstall the Filter Before Use
To clean the Air Filter:
1. Carefully remove the Air Filter from the Motor Air In-Take Cover opening. Do not tear or damage the
Filter (see Figure 5-1: Air Filter Location).
2. Clean the air filter by patting, and shaking the dust from the filter. Compressed air can be used to
blow the dust out of the filter.
3. Inspect the filter for damage. Any damaged Air Filter must be replaced before using the machine.
4. Replace the filter into the Motor Air In-Take Cover.
5. Check to see if the Air Filter is installed properly. The Air Filter should fill the opening in the front of the
Air In-Take Cover and should completely fill the filter cavity.
To replace the Air Filter:
1. Carefully remove the old Air Filter from the Motor Air In-Take Cover opening. NOTE: Pull the Air Filter
thru the opening in the front of the Motor Air In-Take Cover.
2. Inspect the new Air Filter for damage.
3. Place the new Air Filter into the Motor Air In-Take Cover.
4. The Air Filter should fill the opening in the front of the Air In-Take Cover and should completely fill the
filter cavity.
Using the machine with a dirty, damaged, or missing Air Filter will result in motor damage and is not
covered under warranty.
