4. Operating Instructions
Operating the HML400 lift requires careful attention to safety and proper technique.
4.1. Preparing for a Transfer
- Assess the Environment: Ensure the area is clear of obstructions.
- Position the Lift: Roll the lift into position, ensuring the base is adjusted to provide maximum stability and access around the patient's chair or bed.
- Apply Brakes: Lock the casters to prevent unintended movement during the transfer.
- Attach Sling: Securely attach the appropriate patient sling to the sling bar hooks. Ensure the sling is correctly fitted to the patient according to the sling manufacturer's instructions.
4.2. Raising the Patient
- Close Release Valve: Ensure the hydraulic release valve (typically a lever or knob on the pump) is fully closed by turning it clockwise.
- Pump Handle: Use the hydraulic pump handle to slowly raise the boom. The handle can be rotated for operation from either side of the lifter.
- Monitor Patient: Continuously monitor the patient during the lift, ensuring comfort and security. Raise the patient only high enough to clear obstacles.
4.3. Lowering the Patient
- Position Patient: Guide the patient over the target surface (e.g., bed, wheelchair).
- Open Release Valve: Slowly open the hydraulic release valve by turning it counter-clockwise. This will gradually lower the boom.
- Control Descent: Control the rate of descent by adjusting how much the valve is opened.
- Secure Patient: Once the patient is safely seated, unhook the sling from the sling bar.
4.4. Moving the Lift
- Unlock Casters: Release the caster brakes.
- Push, Don't Pull: Always push the lift to move it. Avoid pulling, especially with a patient in the sling.
- Clear Path: Ensure a clear path and avoid sudden movements.
Caution: Never leave a patient unattended in the lift. Always ensure the casters are locked when raising or lowering a patient.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your HML400 lift.
- Daily Inspection:
- Check for any visible damage, loose bolts, or worn parts.
- Ensure casters roll freely and brakes engage properly.
- Verify the hydraulic pump operates smoothly without leaks.
- Cleaning:
Clean the lift regularly with a mild detergent and water. Avoid abrasive cleaners or solvents. Dry thoroughly after cleaning.
- Lubrication:
