THIS MACHINE IS NOT
INSULATED!
USE OF THE AERIAL WORK PLATFORM: This aerial work platform is intended to lift persons and his tools as well as the material used
for the job. It is designed for repair and assembly jobs and assignments at overhead workplaces (ceilings, cranes, roof structures, buildings etc.). All other uses of the aerial work platform are prohibited!
THIS AERIAL WORK PLATFORM IS NOT INSULATED! For this reason it is imperative to keep a safe distance from live parts of electrical equipment!
Exceeding the specified permissible maximum load is prohibited! See “Platform Capacity” on page 4 for details.
The use and operation of the aerial work platform as a lifting tool or a crane is prohibited!
NEVER exceed the manual force allowed for this machine. See “Manual Force” on page 4 for details.
DISTRIBUTE all platform loads evenly on the platform.
NEVER operate the machine without first surveying the work area for surface hazards such as holes, drop-offs, bumps, curbs, or debris;
and avoiding them.
OPERATE machine only on surfaces capable of supporting wheel loads.
NEVER operate the machine when wind speeds exceed this machine’s wind rating. See “Beaufort Scale” on page 4 for details.
IN CASE OF EMERGENCY push EMERGENCY STOP switch to deactivate all powered functions.
IF ALARM SOUNDS while platform is elevated, STOP, carefully lower platform. Move machine to a firm, level surface.
Climbing up the railing of the platform, standing on or stepping from the platform onto buildings, steel or prefab concrete structures, etc.,
is prohibited!
Dismantling the entry gate or other railing components is prohibited! Always make certain that the entry gate is closed and securely
locked!
It is prohibited to keep the entry gate in an open position when the platform is raised!
To extend the height or the range by placing of ladders, scaffolds or similar devices on the platform is prohibited!
NEVER perform service on machine while platform is elevated without blocking elevating assembly.
INSPECT the machine thoroughly for cracked welds, loose or missing hardware, hydraulic leaks, loose wire conne ctions, and damaged
cables or hoses before using.
VERIFY that all labels are in place and legible before using.
NEVER use a machine that is damaged, not functioning properly, or has damaged or missing labels.
To bypass any safety equipment is prohibited and presents a danger for the persons on the aerial work platform and in its working range.
NEVER charge batteries near sparks or open flame. Charging batteries emit explosive hydrogen gas.
Modifications to the aerial work platform are prohibited or permissible only at the approval by Snorkel.
AFTER USE, secure the work platform from unauthorized use by turning the keyswitch off and removing key.
The driving of MEWP’s on the public highway is subject to regulations made under the Road Traffic Acts.
NEVER elevate the platf orm or drive
the machine while elevated unless
the machine is on a firm, level
surface.
ollision Hazard Fall Hazard
NEVER position the platform
without first checking for overhead
obstructions or other hazards.
NEVER climb, stand, or sit on
platform guardrails or midrail.

O
VERLOAD
The AB38 is fitted with a load sensing system designed to comply with the requirements os BS EN 280:
2001
If a load equivalent to 90% of safe working load is lifted a fault code “03” will be displayed on the digital
display on the platform control box. If a load which is greater than the safe working load is present in the
basket all machine functions will cease to operate and an acoustic warning will sound. In order to return to
normal operation a load equal to or less than the saf e w orking load must be present in the bask e t and the
power must be re-cycled, power can be re-cycled by pushing the emergency stop button and releasing it
again.

NOTE: Carefully read, understand and follow all safety rules, operating instructions, labels and National Safety
Instructions/Requirements. Perform the following steps each day before use.
1. Remove the Chassis Covers and inspect f or damage, fluid leaks or missing parts.
2. Check the level of the hydraulic fluid with the platform fully lowered. Remove the Chassis Covers and
remove the reservoir cap, fluid should be visible on the dipstick. Add recommended hydraulic fluid if
necessary. See “Specifications” on page 14.
3. Check that the fluid level in the batteries is correct. See “Battery Maintenance” on page 10.
4. Verify that the batteries are charged.
5. Check that the A.C. extension cord has been disconnected from the chassis outlet.
6. Check that all guardrails are in place and all fasteners are properly tightened.

Always wear safety glasses when working near
batteries.
Battery fluid is highly corrosive. Thoroughly rinse away
any spilled fluid with clean water.
Always replace batteries with Snorkel batteries or
manufacturer approved replacements weighing 26,3 kg
(58 lbs.) each.
• Check the battery fluid level daily, especially if the
machine is being used in a warm, dry climate.
• If electrolyte level is lower than 10 mm
tap water with high mineral content, as it will shorten battery life.
• Keep the terminals and tops of the batteries clean.

WARNING
Charge the batteries in a well ventilated area.
Do not charge the batteries when the machine is near a
source of sparks or flames.
Permanent damage to the batteries will result if the
batteries are not immediately recharged after
discharging.
Never leave the battery charger operating for more than two days.
Never disconn ect the cables from the batteries when the charger is operating.
Keep the charger dry.
1. Check the battery fluid level. If the battery fluid level is lower than 10 mm
distilled water only.
2. Connect an appropriate exte nsion co rd t o charg er outlet plug in Right Module Door. Plug the extension
cord into a properly grounded outlet of proper voltage and frequency .
3. The charger turns on automatically after a short delay. The LED charge indicator will illuminate. After
completion of the charge cycle the LED will blink, indicating that the charger is in a continuing
maintenance mode. DO NOT leave the charger plugged in for more than 48 hours, as permanent
damage to the batteries may occur.
NOTE: The battery charger circuit must be used with a GFI (Ground Fault Interrupt) outlet.
