HYDRAULIC SAFETY TIPS
MAINTAININGA SAFE WORK ENVIRONMENT
Establishing a safe working environment in and around your hydraulic equipment is just common sense. The easiest and most effective way to
avoid problems is to make sure associates understand their equipment, know how to operate it safely and recognize the danger it represents if
handled carelessly.A few things you must be aware of include:
1. PRESSURE: Hydraulic fluid under pressure is dangerous and can cause serious injury.
2. FLAMMABILITY: When ignited, some hydraulic fluids can explode and/or cause fires.
3. MECHANICAL: Hydraulic fluid creates movement, which causes parts of your equipment to move or rotate.Always be aware of what
you are doing.
4. MOISTURE: Use caution when operating in wet or high moisture conditions. Make sure all electrical fittings, switches, cords plus stain
reliefs are in good condition.Always unplug when not in use and when doing any service work.
5. ELECTRICAL: Faulty wiring can also be an electrical hazard.Aregular preventive maintenance program should always include a wir-
ing check. Unplug batteries and/or charger before serving.
6. TEMPERATURE: Because this machine operates at a relatively low pressure, overheating is not common. If surface of tank becomes
too hot to touch by hand (above 130º F, 55° C), shut off machine and allow to cool off.
PRESSURE
Our system runs at or below 2,000 psi. Never look for a leak when unit is under pressure. Using your hand could cause serious injury.Afew
common ways to encounter hydraulic fluid under pressure include:
1. PINHOLE: Fluid under pressure can cause serious injury. It can be almost invisible escaping from a pinhole, and it can pierce the skin
into the body. Do not touch a pressurized hydraulic hose assembly with any part of your body. If fluid punctures the skin, even if no pain is
felt, a serious emergency exists. Obtain medical assistance immediately. Failure to do so can result in loss of the injured part or death.
2. LEAK: Keep fittings and hoses tight. Only check and service when not under pressure. Leaking hydraulic fluid is not only unsightly, it’s
hazardous.Inaddition tomakingworkplace floorsslipperyand dangerous, leaksalsocontaminate theenvironment.Beforecleaning anoil

spill, always check EPA, state and local regulations.
3. BURST: Whether due to improper selection or damage, a ruptured hose can
cause injury. If it bursts, a worker can be burned, cut, injected or may slip and fall.
4. COUPLING-BLOW OFF: If the assembly is not properly made or installed,
the coupling could come off and hit or spray a worker, possibly resulting in serious
injury. Never operate machine without guards.
FLAMMABILITY
With the exception of those comprised primarily of water, all hydraulic fluid is flammable
when exposed to the proper conditions (including many “fire-resistant” hydraulic fluids).
Leaking pressurized hydraulic fluids may develop a mist or fine spray that can flash or
explode upon contact with a cause of ignition. These explosions can be very severe and
could result in serious injury or death.
Precautions should be taken to eliminate all ignition sources from contact with escap-
ing fluids, sprays or mists resulting from hydraulic failures. Sources of ignition could be
electrical discharges (sparks), open flames, extremely high temperatures, sparks caused
by metal-to-metal contact, etc.
HYDRAULIC FLUID
Only use Texaco Rando 46 Hydraulic Oil or Compatible Fluid like IS032. Non-compatible
fluids could cause damage to unit or serious injury.
GROUNDING
Tools marked “Grounding Required” have a three wire cord and three prong grounding
plug. The plug must be connected to a properly grounded outlet (FigureA). If the tool
should electrically malfunction or break down, grounding provides a low resistance path
to carry electricity away from the user, reducing the risk of electric shock.
The grounding prong in the plug is connected through the green wire inside the cord to
the grounding system in the tool. The green wire in the cord must be the only wire con-
nected to the tool’s grounding system and must never be attached to an electrically “live”
terminal.
Your scraper must be plugged into an appropriate outlet, properly installed and grounded
in accordance with all codes and ordinances. The plug and outlet should look like those
in FigureA.
FIG. A
CAUTION: NEVER USE YOUR HANDSTO CHECK FOR LEAKS OVER HOSE
OR HYDRAULIC CONNECTIONS. USEAPIECE OF CARDBOARD TO LOCATE
APRESSURIZED LEAK. FOR LOW PRESSURE LEAKS (DRIPS), USEARAG TO
CLEAN THEAREAAND DETERMINE WHERE THE LEAK ORIGINATES.
WARNING: IMPROPERLY CONNECTING THE GROUNDING WIRE CAN
RESULT IN THE RISK OF ELECTRIC SHOCK. CHECK WITHA QUALIFIED ELEC-
TRICIAN IF YOUARE IN DOUBTAS TO WHETHER THE OUTLETIS PROPERLY
GROUNDED. DO NOT MODIFYTHE PLUG PROVIDED WITH THE TOOL. NEVER
REMOVE THE GROUNDING PRONG FROMTHE PLUG. DO NOT USE THE TOOL
IF THE CORD OR PLUG IS DAMAGED. IFTHE PLUG WILL NOT FITTHE OUTLET,
HAVEAPROPER OUTLET INSTALLED BYAQUALIFIED ELECTRICIAN.

Safety
EXTENSION CORDS
Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord.As the distance
from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 10 gauge cord can carry a higher current than
a 12 gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum
wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the
required minimum wire size.
GUIDELINES FOR USING EXTENSION CORDS
• If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable
for outdoor use.
• Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it re-
paired by a qualified person before using it.
• Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
• Keep away from water. Do not use if wet.
• Inspect thoroughly before each use. DO NOT USE IF DAMAGED.
• Make sure equipment is OFF before connecting cord outlet.
• FULLY INSERT plug into outlet.
• Do not remove, bend or modify any metal prongs or pins of cord.
• Do not use excessive force to make connections.
• Do not connect a three prong plug to a two-hole cord.
• Avoid overheating. Uncoil cord and do not cover it with any material.
• Do not walk on cord.
• Do not drive, drag or place objects over cord.
• National recommends using a single 50’12 gauge extension cord.
