Oil feed line	Tube connecting reservoir to pump and bar
Control button/lever	User-operated mechanism to activate oil flow
Outlet port	Directs oil to the guide bar groove and chain
Sight window	Visual indicator for oil level (on some models)
Filter screen	Prevents debris from entering oil system
Check valve	Prevents oil backflow
Mounting points	For secure attachment to chainsaw body
Compatibility	Designed for specific McCulloch chainsaw models

Installation & Setup

Unpack and inspect all components. Ensure chainsaw is off and cool before installation.

Locate oiler mounting point: Refer to your chainsaw model's manual for exact location.
Attach oiler assembly: Secure using provided screws or clips.
Connect oil feed line: Attach line from reservoir to pump inlet and from pump outlet to bar port.
Fill oil reservoir: Use recommended bar and chain oil. Do not overfill.
Prime the system: Press oiler button several times until oil appears at bar/chain interface.

WARNING! Use only recommended oils. Incorrect oil can damage the system. Ensure all connections are tight to prevent leaks.

Specifications

Type: Manual, positive displacement pump.
Activation: Button or lever (model dependent).
Oil Capacity: Varies by chainsaw model (typically 150-300ml).
Oil Type: High-quality chainsaw bar and chain oil (SAE 30 or equivalent).
Connection: Integrated with chainsaw oil tank or separate reservoir.
Materials: Durable plastic and metal components resistant to oil degradation.
Operating Temp: -10°C to 40°C (14°F to 104°F).
Compatibility: Check your McCulloch chainsaw model number.

Controls and Operation

The manual oiler is operated by the user during cutting. Front Control: Oiler button/lever located near the rear handle or trigger guard.

Operation: Press and hold the oiler button/lever while the engine is running to pump oil to the chain and bar. Release to stop oil flow.

Frequency: Oil frequently, especially when cutting dry, hard, or dirty wood. A good rule is to press the oiler every 30-60 seconds of continuous cutting, or more often as needed. Visual Check: Look for a fine line of oil being thrown from the chain onto your work surface as confirmation of operation.

Connecting to Chainsaw

The oiler is pre-installed on most McCulloch chainsaws. For replacement or repair:

Ensure chainsaw is off, cool, and disconnected from power (if electric) or has spark plug wire disconnected (if gas).
Drain any remaining oil from the reservoir.
Disconnect old oil lines and remove mounting screws.
Install new oiler, reconnect lines (inlet from tank, outlet to bar), and secure mounts.
Refill with oil and prime the system.

Tip: Always use genuine McCulloch replacement parts for optimal fit and performance.

Oiling Procedure

Proper oiling is essential for cutting efficiency and safety.

Pre-Cut Check: Verify oil reservoir is filled. Run chainsaw at idle and press oiler button. Look for oil fling-off at the tip of the bar.
During Cutting: Operate chainsaw at cutting RPM. Press and hold the oiler button/lever for 1-2 seconds every 30-60 seconds, or more frequently in demanding conditions.
Post-Cut: After stopping the saw, wipe excess oil from the bar and chain to prevent dirt accumulation.
Storage: If storing for extended periods, run the oiler to coat the bar and chain, then empty the oil reservoir to prevent gumming.

WARNING! Never operate the chainsaw without adequate bar and chain lubrication. This causes rapid wear, overheating, and potential chain breakage.

Maintenance Schedule

Regular maintenance ensures reliable operation.

Interval	Task
Before each use	Check oil level; test oiler function.
Every 5 hours of use	Inspect oil feed lines for cracks or leaks.
Every 20 hours of use	Clean oil tank filter screen (if accessible).
Annually or as needed	Replace oil feed lines. Inspect pump mechanism for wear.

Use only clean, recommended oil. Dirty or old oil can clog the system.

Safety Features

Manual Control: User determines oiling frequency based on cutting conditions, preventing under- or over-oiling. Durable Construction: Designed to withstand vibration and impacts common in chainsaw use. Fail-Safe Design: Manual operation means no electrical failure can stop oiling (user dependent).

Care & Cleaning

Unplug/disable chainsaw before cleaning. Wipe exterior with a dry cloth. To clean interior/oil passages: Flush with recommended oil. Never use water, solvents, or compressed air which can damage seals.

CAUTION! Oil is flammable. Keep away from sparks, open flames, and heat sources. Dispose of used oil properly.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No oil reaching chain	Empty reservoir, clogged line, air lock, faulty pump	Fill reservoir. Check/clear lines. Prime system. Inspect/replace pump.
Weak oil flow	Low oil, dirty filter, worn pump, wrong oil viscosity	Refill. Clean filter screen. Replace pump. Use recommended oil.
Oil leaking	Cracked reservoir, loose connections, damaged seals	Tighten connections. Replace cracked parts or seals.
Oiler button stiff/hard to press	Gummed oil, internal damage, cold oil	Clean system with fresh oil. Replace if damaged. Allow saw to warm up in cold weather.
Chain still runs hot/bar smokes	Insufficient oiling frequency, wrong oil, worn bar/chain	Oil more often. Use proper oil. Sharpen chain and inspect bar for wear.

Reset: For persistent issues, disassemble, clean all parts with fresh oil, and reassemble.
