1. Engine feels weak under load

Cause: Clogged air filter or dirty fuel injectors.

Fix: Replace the air filter and clean the injectors to restore power.

2. Brakes feel soft

Cause: Air in the brake lines or worn pads.

Fix: Bleed the brake system and replace pads if they're worn down.

3. Hydraulic lift won't raise / is slow

Cause: Low hydraulic fluid, clogged filter, or air in the lines.

Fix: Top up the fluid, replace the filter, and bleed the air from the system.
