SAFETY PRECAUTIONS

Read owner's manual completely before operating unit!

• Never exceed the maximum loading capacity of 880 pounds.

• Stand clear of load while loading and unloading.

• Load must be evenly distributed on deck to insure stability.

• Use caution in moving a loaded unit; avoid obstructions and

floor defects.

• Always apply wheel brakes when unit is not in motion.

• Never go under deck if there is weight on unit.

• Do not continue to pump on the foot lever if the deck is not

raising.

• Remove weight before working on unit.

• Do not use brake fluid or jack oils. Use AW-32 hydraulic oil

or equivalent.

• Use only replacement parts supplied or approved by the

manufacturer.

• Consult factory before performing any modification to the

original equipment.

• Make sure all operator safety labels are in place (p.11).

Do you have a question about the Vestil HYD-5 and is the answer not in the manual?

The provided document is an owner's manual for the HEFTI-LIFT, specifically models HYD-5 and HYD-10, and also includes information for the HYD-10-DC (DC powered) variant. This device is a material handling lift designed to solve ergonomic and material handling problems.

Function Description:

The HEFTI-LIFT is a portable, manually or DC-powered lift designed to raise and lower loads. Its primary function is to assist in lifting and positioning items, thereby reducing manual effort and potential injuries associated with heavy lifting. The HYD-5 and HYD-10 models appear to be manually operated via a foot pump, while the HYD-10-DC is a DC-powered version, offering motorized lifting and lowering capabilities. The lift features a platform or forks assembly to support the load.

For the DC-powered HYD-10-DC, operation involves a constant-pressure (dead-man style) pushbutton control. Pressing the "UP" pushbutton or pulling a lever up activates the power unit to raise the platform, which stops when the control is released. Similarly, pressing the "DOWN" pushbutton or pushing a lever down energizes a lowering valve, allowing the platform to descend by gravity. The motor does not run during lowering.

Important Technical Specifications:

Maximum Loading Capacity: 880 pounds (for the HYD-5 and HYD-10 models, as indicated by the warning label "CAPA400Kgs (880lbs)"). The DC-powered model's capacity is stated on its machine dataplate, but the general warning implies a similar capacity.
Hydraulic Fluid: AW-32 hydraulic oil or equivalent is recommended for the foot pump models. For the HYD-10-DC, an anti-wear hydraulic oil with a viscosity of 150 SUS at 100°F (ISO 32 @ 40°C) or non-synthetic transmission fluid is specified. Brake fluid or jack oils should not be used.
DC Power Unit (HYD-10-DC):
- 12 VCD power unit (motor, pump, manifold, valves)
- 12 VCD battery
- 12 VCD, 5 amp battery charger
Electrical Components (HYD-10-DC): Includes a battery charge indicator, solenoid start switch, key selector switch operator, contact blocks, flush pushbutton operator, lowering valve solenoid, and lowering valve.
Hydraulic Components (HYD-10-DC): Hydraulic cylinder, hydraulic fluid (3 quarts).

Usage Features:

Portability: The presence of wheels (front, rear, and guide wheels) and a brake assembly indicates that the HEFTI-LIFT is designed for mobility within a workspace.
Load Distribution: Loads must be evenly distributed on the deck or forks to ensure stability.
Safety Precautions:
- Never exceed the maximum loading capacity.
- Stand clear of the load during loading and unloading.
- Use caution when moving a loaded unit, avoiding obstructions and floor defects.
- Always apply wheel brakes when the unit is not in motion.
- Never go under the deck if there is weight on the unit.
- Do not continue to pump the foot lever if the deck is not raising (for foot pump models).
- Remove weight before working on the unit.
- For DC-powered units, ensure all personnel are clear of the machine during operation and that no part of any person or object is under the platform before lowering.
- Always carefully watch the lift and its load during operation.
- Do not use the lift if any damage, unusual noise, or malfunction is observed.
- All operator safety labels must be in place and legible.
Battery-Powered Unit Specifics (HYD-10-DC):
- Operates with a 12V DC battery.
- Features a constant-pressure (dead-man style) pushbutton control for raising and lowering.
- The platform raises only while the "UP" button is pressed.
- The platform lowers by gravity when the "DOWN" button is pressed, and the motor does not run.
- Requires charging via a standard 115V receptacle.
- Battery charger cables must not be coiled during operation.
- Proper polarity must be observed when connecting the charger to the battery (ribbed wire to negative, non-ribbed wire to positive).

Maintenance Features:

Regular Inspections: Product safety signs and labels should be periodically inspected and cleaned.
Troubleshooting Guides: The manual includes detailed troubleshooting guides for both the foot pump models (HYD-5 & HYD-10) and the DC-powered model (HYD-10-DC), covering common issues like failure to raise, slow operation, or drifting.
Parts List: Comprehensive parts lists with engineer numbers and quantities are provided for both HYD-5/HYD-10 and HYD-10-DC models, facilitating easy identification and ordering of replacement parts.
Hydraulic System Maintenance:
- Check and fill hydraulic oil as necessary.
- Clean steel balls and seats in check valves if foreign particles are present.
- Bleed air from the hydraulic system if air-locked or spongy operation occurs.
- Consult the factory before performing any modifications.
Battery Maintenance (HYD-10-DC):
- Lead-acid batteries require careful handling due to sulfuric acid and explosive gases.
- Charge batteries in clean, dry, well-ventilated locations.
- Avoid sparks, flames, or metallic objects near batteries.
- Always have fresh water and soap nearby in case of acid contact.
- Operating with low battery voltage can cause premature motor contact failure.
- Check the battery's water level frequently.
- Replace defective cords or wires immediately.
- A fully-charged 12V lead-acid battery should read 12.65 volts; 11.9 volts indicates full discharge.
- Check charger's 115V supply, 10A output fuse, and output with a voltmeter if batteries are not charging.
Qualified Personnel: All troubleshooting, repairs, and maintenance work, especially involving electrical and hydraulic components, should only be performed by qualified individuals trained to understand mechanical devices and their associated circuits.
Safety During Maintenance: Before any maintenance, the deck/forks must be in the lower position, or the platform securely supported with maintenance props. System pressure and power must be removed.
