11. Maintenance, Inspection and Test

Joerns Healthcare recommend a thorough inspection and maximum safe working load test

of the Oxford Dipper and lifting accessories, slings etc. is carried out every six months. The

examination and test should be conducted according to the recommendations and procedures

below. Joerns Healthcare recommend maintenance, inspection and certified testing is carried

out by authorised service dealers only.

NOTE: These recommendations are in compliance with the requirements of 1998 No

2307 Health and Safety: The Lifting Operations and Lifting Equipment Regulations 1998.

This is a UK regulation. Outside the UK please check your local requirements.

• SPREADER BAR: Check the spreader bar for freedom of rotation. Check for firm

attachment to the boom and the operation of the safety latch. Inspect for excessive wear on

the sling hooks and any side suspenders used in conjunction with the spreader bar. Check

the sling retaining disks are fitted and function as intended. Lubricate the central pivot with

a light mineral based grease or food grade spray lubricant.

• BOOM: Check for secure attachment of the boom to the mast. Make sure the mast clamp

screw can be fully tightened and prevents disconnection of the boom from the mast. Check

the boom raising and lowering is smooth and unhindered. Lubricate all pivot points as

necessary with a light mineral based grease. Check for full engagement of the boom ram

pin with the hydraulic ram top. Make sure the boom ram pin is free to pivot on the mounting

brackets. Lubricate if necessary with a light mineral based grease.

• CHAIR SUPPORT TUBE: Confirm the chair support tube is free to rotate but can be prevented

from rotating by tightening the support tube clamp screw. Confirm correct operation of the safety

latch securing the tube to the boom. Lubricate pivots as necessary using a light mineral based

grease. Check the function of the chair retaining latch and ensure the latch pivot is free and

lubricated.

• CASTORS: Check all castors for firm attachment to the chair legs. Check for free rotation

of the castor and the wheels. Remove any build up of threads, hair or fluff. Lubricate if

necessary with a light mineral based grease or food grade spray lubricant. Check correct

operation of the brakes.

• HYDRAULIC UNIT: The hydraulic unit should require no maintenance other than checking

for correct operation in both directions and leakage of hydraulic fluid. Additionally, check the

ram for trapped air/sponginess.

• MAST: Visually examine the mast framework for corrosion or rusting, both externally

and internally, particularly at the base immediately above the lower flange. Check the

mast rotates freely in the floor socket. Lubricate with a light mineral based grease as

necessary. Check the mounting of the hydraulic unit to the mast. Make sure the hydraulic

unit pivots freely. Lubricate if necessary using a light mineral based grease. Following the

6 monthly load test conducted at maximum safe working load, examine the mast for

deformation, particularly at the base.
