Vestil CART-DS-1000 (DC) - Manual (Page 13)

• Pull the bottom of the cylinder out of the push assembly and raise the end up higher than any other
part of the hydraulic system. Rotate the cylinder so the hose port is pointing up.
• Loosen the hose fitting by a ½ turn; then “jog” the motor. Oil and air will sputter from the loose fitting.
Once the air is gone, tighten the fitting and replace the cylinder into the push assembly.

NSPECTIONS
:
Only trained and authorized persons should maintain, repair, adjust and inspect the scissor lift cart. Maintenance
and Inspection personnel should verify that the cart complies with all regulations, codes, and standards that apply
to Industrial Scissors Lifts in the location where the cart is used. The person(s) designated to conduct inspections
by your employer must inspect the cart before it is used for the first time and prior to EACH use thereafter.
Maintenance Props: Use two pieces of 4in. x 4in. timber (or some other
compression resistant material like, for example, 1.5in x 1.5in. square
bar) of sufficient length to allow you to access the underside of the deck.
Fully raise the deck; then insert the props between each roller and the
front of the frame. Arrows in the photograph to the right indicate where
the props should be placed. Press the DOWN button to lower the deck;
release the button when the rollers firmly contact the props and the deck
stops descending.
To remove the props after work is finished, fully raise the deck, and then
remove the props.
(A) Inspect daily for:
1.) Frayed wires;
2.) Oil leaks from the hydraulic system;
3.) Pinched or chafed hydraulic lines;
4.) Damage to or structural deformation of:
y scissor leg weldments, pins, rollers, leg brackets (that connect legs to deck or frame), and
all fastening hardware;
y cylinder or cylinder retention brackets;
y frame weldment;
y castors;
5.) Unusual noise or binding, or evidence thereof;
6.) Labels affixed to the cart.
(B) Inspect monthly for:
1.) Oil level (oil should be 1” to 1½” below the fill hole in the reservoir with the deck fully lowered);
2.) Oil leaks;
3.) Worn or damaged electrical wires or hydraulic hoses;
4.) Pivot point wear;
5.) Roller looseness and wear;
6.) Integrity of the retaining hardware on all rollers and on all pivot point pins.
7.) Looseness, wear, or damage to the casters’ bearings, mounting hardware, or surface material.
8.) Proper water level in the battery (DC units only.)
9.) Unusual noises.
10.) All the information, safety, and warning labels being in place and in good condition.
11.) The need to clean off dirt and debris.
(C) Yearly inspection:
Change the oil if it darkens, becomes gritty, or turns a milky color (indicating the presence of water).
Replace the contaminated oil with anti-wear hydraulic oil having a viscosity grade of 150 SUS at
100°F (ISO 32 at 40°C) such as AW 32 or HO 150 hydraulic oil, or a non-synthetic transmission
fluid. You may use a synthetic transmission fluid if you flush the system with the synthetic fluid
before filling the reservoir.
DO NOT use a cart that is structurally damaged in any way. Structural damage includes, but is
not limited to, bending, warping, cracking or other deformation of one or more of the scissor leg weldments, the
frame, rollers, or the deck (see FIG. 1, p. 5). Restore the cart to normal operating condition BEFORE using it
again.
DO NOT use brake fluid or jack oils in the hydraulic system. If oil is needed, use an anti-wear
hydraulic oil with a viscosity grade of 150 SUS at 100°F, (ISO 32 cSt @ 40°C), or Dexron transmission fluid.
Before inspecting,
performing maintenance on or
repairing the cart, unload the cart,
raise the platform, and install
maintenance props on both sides.
