5. Installation Guide

The following are general steps for replacing the oil pump. Specific procedures may vary slightly depending on your Stihl pole saw model. Always consult your saw's official service manual for precise instructions.

1. Preparation: Ensure the pole saw is clean and stable. Disconnect the spark plug wire. Drain any remaining chain oil from the reservoir.
2. Access the Oil Pump: This typically involves removing the clutch cover, clutch assembly, and potentially other components to gain access to the oil pump housing.
3. Remove Old Pump: Carefully detach the old oil pump, noting the orientation and any connecting hoses or gears.
4. Install New Pump: Position the MOLIG replacement oil pump into the housing, ensuring all connections (e.g., oil lines, drive gear) are correctly aligned and secured.
5. Reassemble: Reinstall all removed components in reverse order. Ensure all fasteners are tightened to the manufacturer's specifications.
6. Refill Oil: Fill the chain oil reservoir with the appropriate type and grade of chain lubricant.

6. Operation and Function Check

After installation, it is crucial to verify the oil pump's proper function before using the pole saw for cutting tasks.

• Initial Start-up: Reconnect the spark plug wire. Start the pole saw engine according to its operating instructions.
• Check Oil Flow: With the engine running at idle, hold the pole saw over a light-colored surface (e.g., a piece of cardboard). Increase the engine speed slightly. You should observe a fine spray of oil being ejected from the guide bar groove.
• Adjust Oil Flow (if applicable): Some pole saws have an adjustable oil pump. If your model does, ensure the oil flow is set correctly for the type of cutting you are performing. Refer to your saw's manual for adjustment procedures.
• Continuous Lubrication: During operation, periodically check that the chain and guide bar remain visibly lubricated.

7. Maintenance

Regular maintenance helps ensure the longevity and reliable performance of your oil pump and pole saw.

• Keep Oil Reservoir Clean: Prevent debris from entering the oil reservoir, as this can clog the oil pump or lines.
• Use Quality Chain Oil: Always use high-quality chain and bar oil recommended by the pole saw manufacturer. Do not use waste oil or motor oil.
• Inspect Oil Lines: Periodically check oil lines for cracks, kinks, or blockages. Replace damaged lines promptly.
• Clean Oil Passages: During routine cleaning of your pole saw, ensure the oil outlet port on the guide bar and the oil passages on the saw body are free of sawdust and debris.
• Winter Storage: If storing the pole saw for an extended period, drain the chain oil reservoir to prevent oil from thickening or becoming gummy.

8. Troubleshooting

If you experience issues with oil flow, consider the following troubleshooting steps:

If troubleshooting steps do not resolve the issue, consult a qualified service technician.
