Follow these steps for safe and effective operation of your lawn mower.

3.1 Starting the Engine

2. Move the mower to a level, clear area away from obstacles.
3. Engage the blade control lever (bail bar) against the handle.
4. Pull the starter cord firmly and smoothly until the engine starts.
5. Once started, release the starter cord. Keep the blade control lever engaged during operation.

3.3 Mowing Functions (4-in-1 System)

Your STIGA Combi 48 SQ offers four versatile cutting options:

• Collection: Attach the 60 L grass bag to collect clippings. The bag features a filling indicator.
• Mulching: Insert the mulching plug (included) into the rear discharge opening. This chops grass into fine particles that return to the lawn as natural fertilizer.
• Side Discharge: Attach the side discharge deflector (included) to direct clippings away from the mower.
• Rear Discharge: Remove the grass bag and mulching plug to allow clippings to be discharged directly from the rear.

3.4 Driving the Mower

This model features rear-wheel drive with Dynamic Speed Control (DSC) for easy maneuverability. Simply engage the drive lever on the handle to activate the self-propulsion. The mower operates at a single forward speed.

4. Maintenance

Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always turn off the engine and disconnect the spark plug before performing any maintenance.

4.1 Cleaning

• Clean the underside of the mower deck after each use to prevent grass buildup, which can affect cutting performance.
• Wipe down the exterior surfaces with a damp cloth. Avoid using high-pressure washers directly on the engine or electrical components.

4.2 Blade Care

Inspect the blade regularly for sharpness and damage. A dull or unbalanced blade can lead to an uneven cut and increased vibration.

• Sharpen or replace the blade as needed. Always use genuine STIGA replacement parts.
• Ensure the blade is balanced after sharpening or replacement.

4.3 Engine Maintenance

• Oil Change: Refer to the engine manual for recommended oil change intervals.
• Air Filter: Clean or replace the air filter regularly, especially when operating in dusty conditions.
• Spark Plug: Inspect and clean the spark plug periodically. Replace if worn or fouled.
